It inactivates the lac repressor and induces synthesis of beta-galactosidase, an enzyme that promotes lactose utilization. IPTG is used to induce expression of cloned genes under control of the lac operon ( see Reference 1). IPTG is an analog of galactose that is non-metabolizable and inactivates the lac repressor to induce synthesis of β-galactosidase in E. coli. The expression of cloned genes under the control of the lac operon is induced by IPTG. It is also a substrate for thigalactoside transacetylase and has been reported to induce penicillinase in bacteria.
adjust Volume to 1.0 ml sterile filter and store at -20°C (dilute 1:10000 for indicator agar plates, e.g. 100 µl IPTG stock per 1 L agar solution, How to make a IPTG – 1 M (100 x) Stock Solution. protocols.io Description Thermo Scientific IPTG (isopropyl-beta-D-thiogalactopyranoside) is a highly stable synthetic analog of lactose. It inactivates the lac repressor and induces synthesis of beta-galactosidase, an enzyme that promotes lactose utilization. IPTG is used to induce expression of cloned genes under control of the lac operon. Dissolve 238 mg IPTG (sigma I-6758) in 10 ml DW for (100mM stock) store in 1 ml aliquotes at -20°C Generally a 1mM solution is an effective amount to induce the pLac promoter region. It should be noted that this may vary over cell strains.

The final concentration of IPTG in indicator plates should be 0.2 mM. Dilute your 50 mg/mL stock 1:500 into growth media to obtain the usual 100 µg/mL antibiotic restriction. IPTG (1M) Dissolve 2.83 g IPTG in 8 mL dH2O. Bring to 10 mL with additional dH2O. Sterilize by passing through a 0.2 µm filter. Freeze at -20 °C.
