Influence of sodium butyrate in LentiPro26-A59 viral production. (a) Viable cell concentration of LentiPro26-A59 cell culture, 24 hours after medium exchange by fresh medium with increasing sodium butyrate concentrations. (b) Volumetric titers of stable LV productions performed using increasing sodium butyrate concentrations. (c) Viable cell concentration over a prolonged cell culture period in the presence or absence of sodium butyrate. The black arrow represents the time point when the medium started to be exchanged by fresh medium with 5 mM of sodium butyrate. (d) Volumetric titers obtained in 24 hours production periods over a prolonged cell culture period in the presence or absence of sodium butyrate. All data shown represents the average ± standard deviation from 2 independent experiments.
