It is also a substrate for thigalactoside transacetylase and has been reported to induce penicillinase in bacteria. IPTG is an effective inducer of protein expression in the concentration range of 100 μM to 3.0 mM. Typically, a sterile, filtered 1 M solution of IPTG is added 1:1000 to an exponentially growing bacterial culture, to give a final concentration of 1 mM. Se hela listan på agscientific.com We generally solve this by inducing at lower concentration of IPTG at 16 degrees overnight.

Make stock solution of IPTG by dissolving 1 g of IPTG in 4 ml of distilled H 2 O. Adjust the volume of the solution to 5 ml with H2O and sterilize by passing it through a 0.22-µm disposable filter.
