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. WebHow much IPTG can I use to induce expression? This can vary somewhat, but we typically suggest a starting range of 0.1–5 mM IPTG. At what OD should I induce my cells? The time of induction can vary widely. Successful experiments using the T7 systems have induced at an OD 600 of 0.1–1.2.
