Effect of post-induction time on the expression level of IFN-CSP in E. coli BL21/pET21b-IFN-CSP. a: SDS-PAGE analyses of IFN-CSP expression at different post-induction time. Lane M: Protein molecular weight marker; Lane 1: E. coli BL21/pET21b-IFN-CSP before induction; Lanes 2–9: E. coli BL21/pET21b-IFN-CSP after induced 1, 2, 4, 6, 8, 10, 12 and 24 h, respectively. b: Percentage and concentration of IFN-CSP were calculated by the target bands in SDS-PAGE (A)
