Cell Line Stability Evaluation
Cell line stability is a critical factor for process scale up. For large-scale commercial manufacturing, cell lines routinely grow for over 25 generations to achieve high-density culture in the 10,000-20,000 liter production bioreactor. Studies to determine cell line stability are performed up to 50 generations. Best performing cell line will be propagated in small suspension culture and scaled to the 5-L bioreactor at interim time points to evaluate cell growth and product yield and determine long-term cell line stability.
