Iptg overnight induction

WebThe overnight culture was normalized to ~1 × 10 9 cells mL −1 with the pre-warmed S7 medium, supplemented with 0.005% Xyl and split. Amp (3 μg mL −1), IPTG (2 mM), or both Amp and IPTG were added and the cells incubated up to 240 min. At the indicated times, IPTG, Amp, or both were removed from the medium and the culture was plated on LB ... 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.
