Figure 5From: Evaluation of pre-induction temperature, cell growth at induction and IPTG concentration on the expression of a leptospiral protein in E. coli using shaking flasks and microbioreactorCorrelation between soluble LigB (131-645aa) expression (mg/L) in E. coli BL21 (DE3) Star™/pAE and cell growth measured at 600 nm (Abs 600nm ). The linear correlation is mg/L = 181 (g dry cell)/L or mg/L = 45.3 Abs600nm, that is, (mg L-1)/Abs600nm = 45.3 = YP/X.Back to article page
