Expert Insights On Cell Line Development

31. Cell Counting Is Growing More Important Amid Advanced Therapy's Rise 4/12/2024

    You can't improve what you don't measure. This discussion explores advances in cell counting technology and the growing number of ways it aids the biotech industry and beyond.

32. Stable Cell Lines: Stepping Stones For Continuous Viral Vector Manufacturing 2/14/2024

    Amid the increasing need for greater volumes of therapeutic molecules, proteins, and viral vectors, a promising technology started to develop — the stable cell line.

33. It's Time To Dethrone CHO When It Comes To mAb Production 2/1/2024

    Let’s be honest — CHO is an expensive, inefficient, and pervasive way to make mAbs. Emerging and evolving alternatives discussed here include microbial systems, which tend toward better efficiency.

34. Novel Approaches For Obtaining High-productivity Clones 1/30/2024

    Let's dig into cell line selection approaches, transposons to increase copy number for the gene of interest, and targeted integration to rapidly obtain high-productivity clones.

35. Developing A Viral Gene Therapy Manufacturing Process 1/23/2024

    There is a growing popularity of adeno-associated virus (AAV) for delivering in-vivo gene therapies, a growing preference of transient transfection systems by biologics companies, and an increasing number of CDMOs offering this system as a platform process. This article describes a transient transfection AAV manufacturing process that uses a triple plasmid transfection strategy into HEK293T cells.

36. Why Lactococcus Lactis Might Be The Best Membrane Protein Factory 11/17/2023

    The bacteria lactococcus lactis has emerged as a promising alternative expression system for membrane proteins, which are difficult to manufacture. L. Lactis is inexpensive and easy to grow. It also doesn't produce endotoxins, which makes it a good fit for therapeutic applications.

37. Balanced Sourcing Of Custom Media/Buffer Formulations: The Case For Outsourcing 8/10/2023

    Nothing is risk-free; now more than ever, all sourcing options have pros and cons that we need to assess to find the best fit. In this first article of a two-part series, we share three compelling reasons to consider outsourcing, along with key considerations for each.

38. How To Build Cell Culture Models With Purpose 8/9/2023

    Building a successful cell culture model has two key requirements — a clearly defined purpose from the outset and good data that support the purpose. This article discusses aspects to consider when characterizing complex cell cultures through modeling.

39. Here's How USP mAb Standards Support Fast-Evolving Platform Approaches 5/24/2023

    Industry-accepted reference materials give drug manufacturers a competitive edge. Data shows that first-in-class mAbs hold a market lead over later entrants. This article discusses the benefits of using well-characterized reference materials instead of spending time and resources to develop them from scratch. 

40. All You Need To Know About Contamination Control Strategies, Part 2 5/22/2023

    In the second of this two-part series, microbiology and contamination control specialists Vanessa Figueroa and Greg Gibb continue discussing best practices in contamination control strategies through the lens of the newly formalized provisions in the EU GMP Annex I. Discussion includes the elements typically found in a CCS, who in your company is responsible for developing the CCS, how often it needs to be evaluated, and more.
