Witrynaboosts the AAV production, improves the packaging efficiency, and keeps the cell health indices. SUMMARY • We have developed a feed medium that can boost the production of AAV by about 10-fold and improve the virus packaging efficiency 67% without compromising cell growth and health WitrynaBy switching to suspension cell culture systems, the aim is 3-fold: reduce batch-to-batch variability by eliminating fluctuating parameters of cell culture (e.g. serum, cell seeding density), simplify downstream harvesting and purification processes, and increase AAV production to treat larger group of patients. c# item is in list
