    Lot-to-lot variability in cytokines and growth factors is a persistent cost and scale-up challenge in cell and gene therapy manufacturing — inconsistent raw materials can undermine process reproducibility long before a product reaches the clinic. Join this webinar for a look at how animal origin-free (AOF) recombinant cytokines and growth factors are being formulated to address these variability and documentation gaps.
