Iptg induction in cell cloning
WebAug 13, 2024 · In brief, after IPTG induction at 37°C, the genes were induced, then the cells were sonicated and centrifuged as described earlier. The inclusion bodies from the pellet fraction were treated with 8M urea and incubated on ice for 30 min. After incubation, the mixture was centrifuged (4000× g, 20 min, 4°C) to separate the supernatant and the pellet. 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.
