    Integrating Cleavage, Deprotection, and TFF: How Asahi Kasei’s THESYS® Platform Is Reshaping Oligonucleotide Manufacturing
    Apr 16 2026
    As demand for DNA and RNA therapeutics continues to accelerate, manufacturers are under increasing pressure to improve efficiency, reduce risk, and scale production without expanding facility footprints. One emerging solution is the integration of traditionally separate downstream steps into a single automated platform. Asahi Kasei Bioprocess, has addressed this need with the THESYS® platform, a suite of oligonucleotide manufacturing technologies designed to streamline workflows from synthesis through downstream processing. In a recent podcast, Sagar Bhatt, Senior Project Engineer at Asahi Kasei Bioprocess America, discussed the development of an integrated system within the THESYS C&D/TFF system combines cleavage, deprotection (C&D), and tangential flow filtration (TFF), and why this shift represents a meaningful evolution in oligonucleotide manufacturing. Rethinking a Fragmented Workflow Historically, oligonucleotide production has relied on a series of disconnected unit operations. Cleavage, deprotection, ultrafiltration, and diafiltration are often performed across multiple systems, sometimes even in different rooms. “Cleavage and deprotection are often carried out using fairly basic setups… and in many cases, they still involve a lot of manual handling,” Sagar explained. “They also typically require additional equipment, like separate tanks, which adds complexity to the process.” This fragmented approach introduces several challenges. Material transfers between systems increase processing time and create opportunities for product loss. In addition, deprotection reactions, particularly for RNA, require careful thermal control due to heat generated during acid addition. “If the rate of the acid addition and resulting temperature rise are not controlled carefully, it can negatively impact the product… and damage product quality.” Facility constraints add another layer of complexity. Because oligonucleotide processing often involves flammable solvents, operations must occur in hazardous environments. However, traditional filtration systems are not typically designed for these conditions, forcing manufacturers to physically move material between areas. Recognizing these inefficiencies, Sagar and his team saw an opportunity to simplify. “By integrating these operations into a single physical equipment and related automation, we could potentially streamline the workflow, reduce handling steps, and significantly improve overall manufacturing efficiency.” From Concept to THESYS® Integration The idea of combining reaction-based and membrane-based processes might seem complex, but Bhatt emphasized that the separation of these steps is largely historical, not technical. “Cleavage and deprotection are reaction steps… whereas TFF is a membrane separation process,” he said. “Though there are different mechanisms involved, they can operate on the same product stream and can share the same fluid handling architecture if designed properly.” Within the THESYS® platform, this integration is enabled through automation and system design that bring multiple unit operations into a single, cohesive workflow. Advances such as closed-loop temperature control, precise dosing, and real-time pressure monitoring allow both reaction and filtration steps to be managed within one system boundary. Equally important was designing the platform for hazardous environments from the outset. “That eliminated the need for intermediate product transfers, which made this integration approach much more practical.” Engineering for Efficiency and Scale One of the most significant engineering challenges was balancing performance with practicality. “Designing the combined system to keep the footprint to a minimum while also taking operability and maintainability into consideration was one of the biggest challenges,” Sagar said. The team also focused on minimizing holdup volume, maximizing product recovery, and ensuring cleanability for GMP operations—all within a compact system design aligned with THESYS®’s broader focus on efficient, scalable manufacturing systems. The result is a platform that delivers efficiency gains primarily by eliminating transfers. “In traditional setups, the material moves between different systems and sometimes even between different rooms,” he explained. “Each transfer adds time, manual handling, and potential product loss.” By consolidating operations into a single THESYS-based system, manufacturers can complete processes sequentially without interruption, reducing both time and risk. Improvements in Safety and Process Control Beyond efficiency, integration significantly enhances safety and control. “Operators no longer need to move material between systems in solvent handling environments,” Sagar said. “Keeping everything inside one enclosed physical system significantly reduces exposure risk and handling errors.” From a control standpoint, a unified ...

  • Advancing Closed-System Performance: How CPC’s MicroCNX® Connectors Enable Scalable Cell and Gene Therapy Manufacturing

    Advancing Closed-System Performance: How CPC’s MicroCNX® Connectors Enable Scalable Cell and Gene Therapy Manufacturing
    Dec 9 2025
    In this podcast, we spoke with Troy Ostreng, Senior Product Manager and David Burdge, Director of Cell and Gene Therapy at CPC about the development of the MicroCNX® aseptic micro-connectors and how they’re helping biopharma teams streamline closed-system operations for cell and gene therapies. What unfolded was a detailed and forward-looking conversation that touched on CPC’s 47-year legacy, the technical demands of advanced therapies, and the company’s plans to drive the future of automation and sterility in manufacturing. A Legacy That Positioned CPC for Today’s Advanced Therapy Boom When asked how CPC’s long history in biologics and hospital environments prepared the company for today’s cell and gene therapy landscape, David took us back to CPC’s roots. “CPC was founded in 1978, so that’s 47 years of innovation within connection technologies,” he said. “The first biologic was released in 1982, synthetic insulin, and we were there supporting the industry with open-format connectors on single-use bags.” From the early development of biologics through the shift to single-use and the rise of stainless-steel/single-use hybrid systems, CPC continuously evolved its connection technologies. They launched steam-through connectors as bioprocessing grew more complex, released their first aseptic connector in 2009, and introduced their first connector specifically targeted for the cell and gene therapy market in 2017. David explained how that history matters today: “Biologics has about a 35-year head start on advanced therapies. So the question becomes, what lessons can we transfer from biologics to cell and gene therapy as that industry grows at three to four times the rate biologics did in its first decade?” That perspective, combining biological manufacturing experience with the needs of new therapy modalities, forms the foundation for CPC’s MicroCNX platform. MicroCNX: The First Aseptic Connector Built for Small-Format Tubing As cell and gene therapy developers began scaling up manufacturing, they quickly discovered a problem: the connectors used for biologics were not designed for small-volume, patient-specific therapies. Troy described it plainly: “Several years ago, we started hearing rumblings that current connectors weren’t meeting what cell and gene therapy required.” CPC responded with a deep Voice of Customer (VOC) initiative, interviewing process engineers, operators, manufacturing leaders, and platform developers. Over and over, the same needs emerged. Operators wanted something simple. “Ease of use was the number one requirement,” Troy said. “Operators needed a product that was easy to use so they could make sterile connections in a short amount of time.” Processes demanded robustness. “Customers needed a connection they could trust—no contamination, no failures, no weak spots in the connection process,” he added. Small-volume precise applications required connectors actually designed for them. With autologous therapies, he noted, “We aren’t talking about 1,000 liters; we’re talking about 250 milliliters. And if there’s a mishap, that could mean the difference between life and death for a patient.” All of this laid the groundwork for MicroCNX, which became the first aseptic connector engineered for small-format tubing. The “Pinch-Click-Pull” Process: Sterility Meets Speed One of the standout features of MicroCNX is its elegantly simple pinch-click-pull operation. Troy explained how simplicity came directly from user feedback. “As operators walked us through their pain points, what they needed was clear: a connector they could learn immediately. So MicroCNX has a three-step process—pinch, click, pull. You can literally do it as fast as I say it.” He continued,“Once someone does it one time, they’re basically an expert. That ease of use dramatically reduces operator error.” For an industry where operator variability remains one of the biggest sources of risk and batch loss, eliminating complexity is critical. Cryogenic Challenges Call for Cryo-Rated Solutions As the conversation shifted to cryopreservation, a critical component of cell therapy manufacturing,Troy introduced the MicroCNX® ULT and MicroCNX® Nano variants. “These were really developed because therapies were being frozen to –150°C, even –190°C. You need a connector that can be frozen to those temperatures, thawed, and still be as robust as it was before.” The ULT and Nano were engineered with: Low-profile geometries to fit inside freezing cassettes Specialized materials to withstand thermal stress Chemical compatibility with DMSO and other cryoprotectants Enhanced durability to survive impacts while frozen Troy emphasized how critical it was to get the materials right: “We searched extensively for a material that could handle those harsh chemicals and temperatures. What we landed on was PPSU—polyphenylsulfone. It’s chemically sound, and it’...

  • Inside ATLAS – Transforming Surfactant Monitoring in Bioprocessing

    Inside ATLAS – Transforming Surfactant Monitoring in Bioprocessing
    Aug 20 2025
    Surfactants are indispensable in the production of biologics, vaccines, and cell therapies. Yet for years, they’ve posed a persistent challenge: they are notoriously difficult to monitor accurately and in real time. That challenge is now being addressed by Nirrin and its groundbreaking Atlas platform, a real-time spectroscopy solution that is reshaping how biomanufacturers measure and manage surfactants. In this episode of The Cell Culture Dish podcast, Editor Brandy Sargent spoke with Bryan Hassell, Founder and CEO of Nirrin, and Hannah Furrelle, Analytical Scientist at the company, to discuss the science behind Atlas and its implications for bioprocessing. Real-Time Data Without Compromise At the core of Atlas’s innovation is its ability to provide high-quality quantitative data in under a minute—without any sample preparation. “The real breakthrough with Atlas is speed with confidence,” explained Hassell. “Time to market for biopharma is increasingly critical, yet a lot of critical decisions still rely on data from assays that take days or even months. Atlas changes that.” Unlike traditional techniques, which often require significant sample manipulation and suffer from matrix interference, Atlas uses high-precision tunable laser spectroscopy to directly analyze samples in their native form. “What makes Atlas so powerful is that we’re looking at the sample without altering it,” Furrelle explained. “That means the data we get is true to the process—there’s no distortion from prep steps or artifacts introduced by the method.” Moving Beyond PLS: A New Modeling Approach One of the technological breakthroughs enabling this leap in performance is Nirran’s move away from PLS models in favor of an iterative optimization framework. This approach eliminates the need for extensive training data, reducing model complexity while increasing robustness and flexibility. “Where a PLS model might need 20 to 30 bioreactor runs to build a dataset, Atlas delivers data on the fly,” Hassell said. “It’s not only faster, it’s more robust, more compliant, and more versatile—especially for applications like scale-up or tech transfer, where traditional models often break down.” Applications Across the Biomanufacturing Workflow Atlas is already being integrated into real-world bioprocessing environments, including both batch and continuous manufacturing. In batch processes, manufacturers use Atlas to confirm critical parameters—like protein and excipient concentrations—before proceeding to the next unit operation. This enables earlier course corrections and helps prevent downstream failures. “In the past, you either waited days for lab results or moved forward at risk,” said Hassell. “Atlas provides the immediate answers needed to make confident decisions in the moment.” For continuous manufacturing, the value is equally profound. Atlas provides the real-time, quantitative feedback necessary for dynamic process control. “You can’t have continuous processing without real-time data,” he said. “Atlas gives you the insights needed to support real-time decisions at every step.” Eliminating Risk with No-Prep Analysis One of Atlas’s standout features is its ability to deliver no-prep analysis. This eliminates sources of variability that often arise during sample handling and processing. “We’re scanning samples in their native form,” said Furrelle. “That means what we’re measuring reflects what’s actually in the process—without distortion from dilutions or centrifugation.” This no-prep capability also speeds up workflows and eliminates risk by allowing operators to verify component concentrations instantly before committing to the next step in production. Laying the Foundation for Smart Biomanufacturing Nirrin sees Atlas not just as a data tool, but as a stepping stone to smart biomanufacturing. Although full automation isn’t yet widespread, Atlas is helping to lay the groundwork by delivering trustworthy real-time data, something most operations have historically lacked. “Right now, we’re focused on validating the technology and educating the industry,” said Hassell. “Without sensors like ours, you can’t have smart manufacturing. But once real-time data becomes available, everything else,automation, digital twins, AI,can start to fall into place.” Furrelle agreed, adding, “You can’t automate without sensors. Atlas gives you real-time insights that teams can actually use, not work around.” From QC Tool to Strategic Platform As teams adopt quality-by-design (QbD) approaches, Atlas is being used well beyond its initial QC role. It’s becoming a platform for optimizing surfactant levels, improving batch-to-batch consistency, and proactively preventing formulation issues. “You can’t have quality if you don’t start from a place of quality,” Furrelle said. “Validating components before you use them is no longer just ideal, it’...

  • From Storage Tanks to Smart Systems: The Evolution of Buffer Preparation

    From Storage Tanks to Smart Systems: The Evolution of Buffer Preparation
    Apr 30 2025
    In this podcast, we spoke with Nainesh Shah, Sr. Application Engineer, Asahi Kasei Bioprocess America, about how inline buffer formulation and their MOTIV® system offers a more efficient, scalable, and cost-effective approach to buffer preparation. Traditional methods require large storage spaces, pose risks of leakage, and create inefficiencies that can disrupt production. In contrast, inline buffer formulation enables real-time mixing of concentrated ingredients, eliminating storage constraints and allowing for dynamic adjustments based on demand. With benefits like reduced waste, lower costs, and improved regulatory compliance, this technology is streamlining operations while ensuring precision and adaptability. As the industry shifts toward smarter manufacturing solutions, inline buffer formulation is paving the way for the future of pharmaceutical production. How Inline Buffer Formulation is Changing the Industry Nainesh, who has over 40 years in the pharmaceutical industry and six years at Asahi Kasei, highlights the evolution of buffer preparation. "Traditionally, buffer dilution involved a concentrate formulated in advance, which was then diluted with water to achieve the desired solution.” Modern inline buffer formulation transforms this process by enabling real-time mixing of individual components. "Instead of storing pre-made buffer solutions, MOTIV allows for real-time formulation using individual components. The system precisely combines these ingredients on demand, ensuring accuracy and eliminating storage-related inefficiencies," Shah explains. Enhanced Efficiency, Cost Savings, and Waste Reduction The advantages of MOTIV extend beyond storage and formulation flexibility. "With traditional methods, production can be delayed if pre-made buffers aren’t readily available. If a change in concentration or formulation is required, additional time is needed for sourcing and preparation," Shah notes. "With MOTIV, you can use a single concentrated solution to create multiple buffer variants by adjusting the dilution ratio. This eliminates the need for multiple pre-concentrated stocks, reducing storage space, waste and increasing efficiency." Cost efficiency is another crucial factor. "Return on investment (ROI) depends on whether the facility has an existing buffer preparation setup or is installing a fresh system. For existing setups, ROI typically takes around two years due to transition considerations. However, for new installations, ROI can be achieved within 1.5 years," Shah states. He adds that Asahi Kasei provides an easy-to-use ROI calculator to help companies assess their financial benefits. Additionally, inline buffer formulation improves sustainability by minimizing waste and reducing the environmental impact of excess buffer storage. By eliminating the need for large buffer stockpiles, facilities can lower their material costs and optimize resource utilization. Scalability and Customization for Diverse Production Needs One of the standout advantages of the MOTIV inline buffer formulation system is its scalability. "Our smallest system supports up to 1,200 liters per hour with three inlets—one for water and two for concentrates like acid, base, or salt solutions. On the higher end, we can scale up to 5,000 or even 12,000 liters per hour, completely customizable with multiple inlets based on customer requirements," says Shah. This flexibility is particularly valuable for pharmaceutical manufacturers with varying production demands. Facilities producing multiple types of buffers can benefit from the system’s adaptability, allowing them to switch formulations with minimal downtime. Instead of maintaining separate storage tanks for different buffer types, inline buffer formulation enables dynamic adjustments based on real-time requirements. Addressing Complex Formulations and Space Constraints MOTIV is particularly beneficial for high-volume buffer requirements and complex formulations. "As pharmaceutical processes advance, buffers require multiple ingredients, not just simple acid-base-salt combinations. MOTIV automates these complex formulations with precision, ensuring consistency while reducing human error," says Shah. Moreover, these systems help optimize space usage. Traditional buffer preparation requires large storage tanks, which can be a logistical challenge for facilities with limited space. By replacing bulky storage units with a compact inline formulation system, pharmaceutical companies can free up valuable floor space for other critical operations, leading to improved overall facility efficiency. Streamlining Global Operations and Regulatory Compliance MOTIV enables pharmaceutical companies to streamline global operations. "A single facility’s buffer formulation data can be easily transferred to other locations, reducing the need for redundant validation and documentation. This simplifies global production expansion while maintaining quality and compliance," says ...

  • Unlocking the Potential of Induced Pluripotent Stem Cells: Innovations, Challenges, and Future Directions

    Unlocking the Potential of Induced Pluripotent Stem Cells: Innovations, Challenges, and Future Directions
    Jan 22 2025
    In this podcast, we spoke with Dr. Jorge Escobar Ivirico, Product Manager, Bioprocess Solutions at Eppendorf, about the fascinating world of induced pluripotent stem cells (iPSCs), exploring their groundbreaking potential in regenerative medicine, personalized therapies, and drug development. Our guest explained how iPSCs, created by reprogramming adult somatic cells, can differentiate into virtually any cell type, making them invaluable for research and therapeutic applications. We delved into the importance of consistency, quality control, and reproducibility in iPSC production, alongside the challenges of culturing these cells, such as maintaining pluripotency and scaling production for clinical use. The discussion highlighted exciting advancements, including the development of organoids and universal T cells, as well as the ethical considerations distinguishing iPSCs from embryonic stem cells. Looking to the future, Jorge envisioned iPSCs becoming a cornerstone of standard medical practice, while acknowledging the need to address safety, scalability, and regulatory hurdles to fully realize their potential. What are Induced Pluripotent Stem Cells (iPSCs)? "Induced pluripotent stem cells are a type of stem cell created by reprogramming adult somatic cells, like skin or blood cells, back into an embryonic-like state," explains Jorge. This process involves introducing specific transcription factors, often called Yamanaka factors, to transform these cells into a versatile state. Once reprogrammed, iPSCs can differentiate into almost any cell type, making them invaluable tools for research, drug development, and potentially life-changing therapies. The Growing Importance of iPSCs iPSCs offer a range of advantages, particularly their ability to sidestep ethical concerns tied to embryonic stem cell use. “What makes iPSCs so important today,” Jorge notes, “is their versatility and potential applications. Researchers can create patient-specific cell lines, which are essential for drug screening, disease modeling, and personalized medicine.” This technology is pivotal for regenerative medicine, offering hope for repairing damaged tissues and organs. “From neurodegenerative diseases to heart damage, iPSCs open the door to innovative treatment possibilities,” he adds. Mastering the Production Process Producing iPSCs is a meticulous endeavor. "Consistency is key," emphasizes Jorge. Researchers must ensure that each batch of cells meets strict criteria to avoid unpredictable outcomes, especially when precision is vital in both research and therapeutic applications. Standardized protocols and quality control measures are essential to achieve consistency. These involve monitoring for contamination and verifying the cells' ability to differentiate into various cell types. “Imagine developing a therapy based on a specific batch of cells, only to find that subsequent batches behave differently,” he warns. “Such inconsistencies can jeopardize patient outcomes.” Tackling Challenges in Culturing iPSCs Culturing iPSCs presents its own set of challenges. High cell numbers are often needed for large-scale research or therapeutic applications, but scaling up production without compromising quality is no small feat. Maintaining the cells’ pluripotent state is another hurdle, as they can easily differentiate prematurely under certain culture conditions. "Environmental parameters like temperature, pH, oxygen levels, and nutrient availability must be rigorously controlled," Jorge explains. “Even minor fluctuations can negatively impact cell health and their ability to remain pluripotent.” Innovations Addressing Culturing Hurdles To overcome these challenges, researchers are turning to advanced techniques like 3D culture systems and bioreactors. These provide a more natural growth environment for the cells, enhancing their viability and functionality. “By transitioning from traditional 2D cultures to 3D systems, we can better mimic the natural environment, significantly improving outcomes,” Jorge shares. 3D systems also increase growth surfaces for cell attachment and allow for higher cell density, which is critical for producing the large quantities required for therapies. "It’s not just about quantity," he notes. "These systems help maintain the quality of the cells, ensuring consistent results across labs and facilities worldwide." Transformative Applications of iPSCs One of the most exciting applications of iPSCs is in creating universal T cells for therapies like CAR-T cell treatments. “Traditional CAR-T therapies require harvesting a patient’s cells and modifying them—a time-intensive process that isn’t suitable for all patients,” Jorge explains. "With iPSCs, we can create a bank of genetically modified T cells that can be used across multiple patients, reducing risks like graft-versus-host disease and speeding up treatment timelines." Balancing Potential with Risk Despite their ...

  • Accelerating Bioprocess through Digital Transformation: A Strategic Path Forward

    Accelerating Bioprocess through Digital Transformation: A Strategic Path Forward
    Dec 12 2024
    In an era where industries are increasingly driven by data and automation, the bioprocessing sector is embracing digital transformation to streamline workflows and improve productivity. However, blending the complex and highly regulated world of bioprocess with digitalization poses unique challenges. In this podcast, we talk to Dr. Simon Wieninger, Head of Portfolio and Applications at Eppendorf SE about how the journey toward digital integration requires well-defined goals, user-centered design, cross-industry learning, and, crucially, trust. Setting Clear Goals: Purpose-Driven Digitalization “Digitalization shouldn’t happen for digitalization’s sake,” Dr. Wieninger advises. While the temptation to adopt cutting-edge technology is high, each digital tool or system must serve a specific purpose. For bioprocessing organizations, establishing these objectives upfront is critical to ensure that digital investments yield meaningful results. Whether the aim is to boost productivity in production facilities, refine R&D processes, or improve operational efficiency in support functions like HR, having clearly defined goals anchors digital efforts in purpose. This intentional approach is especially significant for production and R&D sectors within bioprocessing. Here, digitalization can streamline processes such as real-time data monitoring, automated adjustments to culture environments, and improved reporting and compliance tracking. By aligning digital goals with broader business objectives, organizations can make more effective use of resources and ensure that digitalization contributes positively to organizational growth. Bridging Skill Gaps and Building Trust: Making Digital Tools Accessible A successful digital transformation relies on the people who will use these tools day-to-day. However, not everyone in bioprocessing has a background in software or programming. Simon points out that for digital tools to be effective, they must be intuitive and accessible to all team members, from scientists in the lab to technicians on the production floor. "We need to design solutions that everyone can use," he says, noting the importance of user-friendly interfaces that require minimal technical knowledge to operate. Part of building an accessible digital framework is understanding the varying comfort levels with technology within the workforce. Some employees may be tech-savvy, while others are less familiar with digital tools. Recognizing and accommodating these differences is crucial to creating a smooth transition. Moreover, as Simon explains, trust is fundamental—not only trust in digital tools but also in the partnerships with vendors and technology providers who support this transformation. Organizations should leverage the expertise of these partners, building collaborative relationships to create solutions that meet specific needs and ultimately make bioprocess workflows more efficient. Learning from Other Industries: Adopting Best Practices in Automation and Standards The bioprocess industry has much to learn from sectors like automotive, finance, and telecommunications, which have long relied on automation and standardized processes to boost efficiency. In automotive manufacturing, for instance, high levels of automation allow for the production of thousands of vehicles with minimal human intervention. Bioprocessing, by contrast, has historically been more manual and labor-intensive, particularly in R&D and small-batch production. According to Simon, one of the greatest opportunities for bioprocessing is to adopt industry standards that facilitate automation and improve interoperability across devices. One such example is the OPC (Open Platform Communications) standard, widely used in other sectors for seamless communication between devices. Applying such standards to bioprocessing could simplify data integration across lab instruments and production equipment, allowing researchers to capture and analyze critical information more efficiently. Additionally, industry leaders could set standards for digital protocols and automation practices, which would pave the way for faster digital adoption across the field. Addressing Regulatory Challenges: Transforming Compliance through Digitalization The bioprocess industry operates under stringent regulatory standards, which some view as an impediment to digital innovation. However, Simon argues that regulatory requirements shouldn’t be seen as obstacles but rather as factors that digital solutions can help address. In industries like finance and insurance, also highly regulated, companies have successfully incorporated digital tools to streamline compliance. Similarly, in bioprocessing, digital platforms could help standardize and organize the data needed for regulatory filings, potentially reducing the time and resources required for compliance. Digital solutions, including cloud-based platforms and automated data management systems, could be ...

  • The Key to Biologics Success: Why Developability Assessments Matter in Antibody Discovery

    The Key to Biologics Success: Why Developability Assessments Matter in Antibody Discovery
    Nov 21 2024
    In this podcast, we spoke with Dr. George Wang, Vice President of Discovery and Preclinical Services at WuXi Biologics about the importance of identifying potential manufacturing, stability, and scalability challenges early to mitigate risks, reduce costs, and streamline drug development timelines. By evaluating factors such as solubility, stability, and manufacturability during initial candidate screening, companies can avoid costly setbacks later in the process. Advanced tools like high-throughput assays, computational modeling, and AI-based predictions are now essential for these evaluations. What Is Developability? Dr. Wang began by defining developability as the assessment of whether a drug candidate possesses the necessary attributes to be scaled up for production during Chemistry, Manufacturing, and Controls (CMC) development and, ultimately, for clinical trials and commercialization. He explained, “It’s about identifying potential red flags early on—issues like aggregation, degradation, or manufacturing inefficiencies—that could derail a candidate further down the line.” Why Focus on Developability During Discovery? Traditionally, discovery efforts have focused on identifying antibodies with the highest efficacy and safety profiles. However, the increasing complexity of biologics, including bispecific antibodies and antibody-drug conjugates, has shifted industry focus. Dr. Wang emphasized the costly consequences of overlooking developability in the discovery phase. “Imagine investing millions into a molecule, only to discover insurmountable stability or manufacturability issues during development,” he said. “Performing these assessments early is like an insurance policy, mitigating risks and saving time and resources.” The Economic Case for Early Developability Assessments Dr. Wang highlighted the economic rationale for incorporating developability assessments during the initial discovery phase. “The cost of discovery is less than 1% of the total development cost. Spending a bit more upfront can save millions in reengineering or restarting development,” he noted. He also pointed out that superior developability attributes can provide a competitive edge, enabling faster clinical trial entry or product approval. Key Challenges and Industry Solutions Despite its benefits, the integration of developability assessments in discovery labs faces challenges. Labs often lack the tools, materials, and expertise required for systematic evaluations. “Developability attributes must be assessed using a robust combination of computational methods, analytical tools, and high-throughput assays, which many labs are not equipped to handle,” Dr. Wang explained. Companies like WuXi Biologics have stepped in to bridge this gap. “Our Discovery unit collaborates closely with our CMC team to identify and address developability issues early on,” said Dr. Wang. WuXi’s “WuXiDEEP™,” platform has become a cornerstone of their success, helping fix more than 50 problematic molecules and guiding hundreds of projects through the development pipeline. A Stepwise Approach to Developability Dr. Wang outlined a stepwise approach to developability assessments, starting with high-throughput evaluations during the initial screening of hundreds of candidates. “We use computational analysis to identify red flags such as post-translational modification hotspots or aggregation risks,” he explained. Promising candidates then undergo more detailed assessments, requiring larger material quantities and lower-throughput methods. Even when issues arise, solutions like protein engineering can salvage candidates with strong biological functions. “It’s not about discarding problem molecules outright but addressing and optimizing their developability profiles,” Dr. Wang emphasized. The Role of AI in Developability Assessments Artificial intelligence (AI) is playing an increasingly significant role in drug discovery, and Dr. Wang underscored its potential in developability assessments. “AI-based modeling and prediction tools enable us to anticipate developability challenges early, optimizing the process even further,” he said. Practical Impact and Case Studies Dr. Wang discussed the webinar he gave, Developability Assessment and Optimization in Antibody Drug Discovery, in which he shared case studies that demonstrated the transformative power of early developability assessments. From rapid decision-making to optimized engineering solutions, these examples illustrated how WuXi Biologics helps clients navigate the complex landscape of biologics development. Final Thoughts As the biologics industry continues to evolve, developability assessments have become indispensable for reducing costs, saving time, and maintaining competitive advantages. Dr. Wang’s insights underscore the importance of integrating this approach during the discovery phase, laying a strong foundation for successful drug ...

  • New Cell Culture Select Tool Simplifies Cell Culture Selection for Researchers

    New Cell Culture Select Tool Simplifies Cell Culture Selection for Researchers
    Nov 13 2024
    In this podcast, we spoke with Isha Dey, Senior Scientist, Cell Biology R&D, at Thermo Fisher Scientific about the challenges researchers face in selecting appropriate cell culture conditions due to variability in cell lines, lack of standardized protocols, and inconsistent reagent quality. Thermo Fisher Scientific's new Cell Culture Select Tool was developed to address these challenges by providing specific recommendations for media, FBS, and cultureware for over 150 cell lines, backed by extensive R&D data. Understanding the Challenges in Cell Culture Selection Thermo Fisher Scientific's new Cell Culture Select Tool addresses a persistent challenge in laboratory science: identifying the appropriate cell culture conditions and selecting the right media, supplements, and reagents for different cell lines. The process is complicated by factors like cell line variability, lack of standardized protocols, and inconsistent reagent quality. These issues can introduce variability and impact experimental results, posing a challenge for scientists across labs. “Different cell lines have unique requirements,” explained Isha. “It’s challenging to pinpoint optimal culture conditions due to variability in cell line responses. Additionally, there isn’t always a standardized protocol across labs or comprehensive information on specific culturing needs. This can make it difficult to select the most appropriate media, supplements, and other materials.” Ensuring a consistent supply of high-quality products is essential for reproducibility in experiments. Thermo Fisher Scientific's trusted brands, such as Gibco, Nunc, and Invitrogen, are known for their quality, which is critical for minimizing variability in experimental readouts. The Inspiration Behind the Cell Culture Select Tool The idea for the Cell Culture Select Tool originated from an update to Thermo Fisher Scientific's online technical reference library. Previously, the website listed recommended media types segmented by cell line culture methods—adherent, semi-adherent, or suspension. While helpful, this list was lengthy and lacked interactive functionality. Isha said, “We realized that we could streamline this information into a user-friendly tool”. “In our R&D labs, we culture over 150 cell lines using various media, supplements, and equipment. By making this data accessible to other researchers through an interactive tool, we hoped to eliminate the guesswork and enable reproducible cell culture success.” The tool now provides recommendations for specific media, supplements, and cultureware for culturing, passaging, and freezing over 150 cell lines. With in-house data supporting 75% of these lines, researchers gain access to the resources and insights gathered from Thermo Fisher’s extensive R&D experience. Selecting Cell Lines for the Tool The team started with cell lines listed in their technical reference webpage and expanded the list based on the lines frequently cultured in their R&D labs. These labs conduct heavy cell culture work for various applications, including media development, fluorescence imaging, Western blotting, flow cytometry, transfection, transduction studies, and more. “We wanted to make our R&D data available to researchers for convenience,” shared Isha. “This effort involved many scientists across R&D sites who contributed data and images showing how each cell line appears in recommended media.” Quality and Verification in Thermo Fisher’s Labs The tool’s data is backed by rigorous testing in Thermo Fisher’s R&D labs. Cells are grown in their respective media, culture plastics, and consumables over multiple passages to ensure accuracy. For cancer cell lines, STR profiling and mycoplasma testing are conducted regularly, while stem cell cultures are assessed for pluripotency and purity using imaging and flow cytometry. “Representative images of cell lines, captured using our EVOS imaging system, are available in the tool to help users understand how cells should look in the recommended media,” said the spokesperson. This visual support is particularly helpful for researchers new to specific cell lines, as it aids in verifying successful cultures and maintaining reproducibility. Future Updates for the Tool Thermo Fisher plans to continuously update the tool by adding new cell lines and products as they become available. Recent updates included new products like the Gibco CultureCEPT Supplement and Nunc cultureware with Nunclon Supra surface. “The Gibco CultureCEPT Supplement, for example, reduces cellular stress and improves viability during handling and processing steps where cell damage and death could occur,” explained the representative. “Meanwhile, the Nunclon Supra Surface simplifies work with complex cell lines and primary cells by enhancing attachment and morphology.” These updates reflect Thermo Fisher’s commitment to innovation, responding to evolving research needs with ...
