Fed-batch cell culture process optimization
WebApr 7, 2024 · This research work is focused on intensified processes with high seeding density inoculated from seed bioreactor in fed-batch mode. The impact of the feeding strategy and specific power input (P/V) in the seed bioreactor and on the production step with two different cell lines ( CL1 and CL2 ) producing two different monoclonal … Webmethodology with a quadratic process model. Criteria for optimization were VCC and viability of the cell population (Figure 1A). VCCs up to 45 million cells/mL were obtained, which is twice the number of cells compared to the previous fed-batch process. With the medium blends PF1_DoE4 and PF1_DoE8, viability and VCC were high over
