Figure 2From: Stable high volumetric production of glycosylated human recombinant IFNalpha2b in HEK293 cellsKinetics of cell growth and IFNα2b production from D9 clone in fed-batch culture. D9 cells were seeded at a cell density of 0,25 × 106 cells per mL, fed with 0,1% TN1 the next day and sampled every day. A) Coomassie-stained SDS-PAGE analysis of the culture medium (20 μL) collected daily. B) Cell counts and viability were measured at the indicated times.Back to article page
