Fig. 5From: Elimination of N-glycosylation by site mutation further prolongs the half-life of IFN-α/Fc fusion proteins expressed in Pichia pastoris Anti-proliferative activity of IFN-α/Fc fusion proteins. Daudi cells were incubated for 72 h in the presence of increasing concentrations of the indicated samples with triple parallel wells in 96-well plates. Cell proliferation was assessed using the MTT method. All data are presented here as mean ± standard deviation of the OD valuesBack to article page
