or buy 25 mL 1M stock solution Teknova 13431 (Fisher) Store at -20C 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 ( 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.

You can prepare a stock solution of 0.5M IPTG and use 1ul for each ml. Meaning if your sample is 100 ml, you can use 100 ul from your stock. Usually works just
