Webfrom cell-based potency assays are expressed as “relative potency” as determined by comparison of test samples to the response obtained for the reference standard. Developing a Cell-Based Potency Assay When developing a cell-based potency assay, careful consideration needs to be taken in selecting the appropriate cell line. First and WebIdeally, a potency assay will leverage the product's mechanism of action. Alternatively, the assay may focus on a therapeutically relevant biological activity. The absence of rigorous mechanistic data for the majority of cell-based therapeutics currently in the process research pipeline has impeded efforts to design and validate indices of ...
