WebIPTG is added to a final concentration of 0.4 mM for induction of protein expression. Before the addition of IPTG, an aliquot of cell culture should be removed and incubated separately as an uninduced control (sample 1, uninduced). Initially induction at 37°C for 2-4 hours can be tested for expression and solubility. WebDec 14, 2024 · After IPTG induction (3 h for sfGFP, Hmp100-sfGFP, and Hmp-sfGFP, 1 h for LacZ and Hmp-LacZ), cell cultures were centrifuged at 15,000 rpm for 3 min, and resuspended in Milli-Q water. The OD 600 of each sample was measured to make sure similar cell numbers were loaded into each well. Afterward, samples were mixed with 2× … Web6.Add IPTG to a final concentration of 1 mM. Optimal time for induction of the target protein may vary from 2-16 hours, depending on the protein. 7.Incubate with shaking at 120 rpm at 37℃ for 3-4 hours. employers annual return
