Natural killer (NK) cell therapy is a rapid emerging field with several advantages over chimeric antigen receptor (CAR) T-cells for cancer treatment. Like any biotherapeutic drug, cell-based therapeutics must also undergo tight scrutiny for their critical quality attributes (CQAs). There are different criteria evaluated for drug purity, with the presence of visible and sub-visible particulate matter being one of them. Particulate impurities can affect drug efficacy and stability but can cause undesirable immunogenicity and toxicity when injected. In this webinar, we will showcase Micro-Flow Imaging (MFI) as a sub-visible particle analysis solution to differentiate NK cells and its expansion components with either irradiated K-562 feeder cells or Cloudz™ microspheres.
Attendees will learn about:
- Considerations regarding the methodology of NK cells expansion
- Identifying sources of particle contamination from ancillary materials
- Showcasing MFI analysis of NK cells from irradiated K-562 feeder cells or Cloudz™ microspheres
