Figure 1From: Study of a recombinant CHO cell line producing a monoclonal antibody by ATF or TFF external filter perfusion in a WAVE Bioreactor™Viable cell density (●, ○), viability (▲, △) and perfusion rate (■, □) in perfusion processes using ATF system (A) and TFF system (B). Closed symbols indicate the ATF9 perfusion experiment, whereas the open symbols represent the ATF15 and TFF10 perfusion experiments.Back to article page
