WebIPTG is a non-metabolizable analog of galactose that induces the expression of lacZ gene. It should be noted that IPTG is not a substrate for β-galactosidase but only an inducer. For … WebInoculate starter culture at a 1:100 dilution into expression media containing antibiotic. Incubate at 37°C with shaking until OD 600 reaches 0.4–0.8. For most vector systems, induce with 40 or 400 μM IPTG and express protein for 3 hours at 37°C, 5 hours at 30°C or overnight at 16°C or 23°C.

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).
