WebBut many times the E.coli cells die (OD600 drops to 0.1 - 0.2) before we can start harvesting: before we start induction, so before OD600 = 0.5 or within an hour after induction with 0.4 mM IPTG. WebInduction was completed by commonly performed one-point addition of IPTG to a final concentration of 0.1 mM [35, 36]. Strain physiology and product-related data were …

WebBL21-DE3- pLysS cells carrying the pRSETA-M1 plasmid was grown in LB media at 37°C and induced with different concentrations of IPTG such as 0.12mM, 0.25mM, 0.5mM and 1mM.
A commonly used protocol would specify how much IPTG to add into growth medium containing the bacterial culture. For GoldBio’s protocols, use 1mM of IPTG in 1 ml of LB medium to make a final concentration of 0.5mM in the medium with bacterial culture.
