Direct Inoculum of Bioreactors with CHO Cells from Frozen Seed Bags to Eliminate Continual Seed Trains & Improve Facility Utilization
Flexibility in cell culture manufacturing via a reduction in process duration can be a key strategy for maximizing facility utilization and facilitating the production of multiple therapeutics from a facility. A key bottleneck is the seed train, which can add weeks to the timeline of the production culture. Seeding production bioreactors with a direct, cryopreserved CHO cell inoculum could possibly eliminate the need for a lengthy, continuous seed train and provide other numerous benefits.
At this year’s Boston Biotech Week, two feasibility studies were presented that showed the use of a Frozen Seed Bag (FSB) for direct cell inoculum into a production bioreactor. Shahid Rameez of KBI Biopharma and Nikhil Ramsubramaniam of Merck presented separate studies demonstrating the use of frozen inoculum in fed-batch production bioreactors (KBI) or perfusion bioreactors (Merck).
