Ambion™ IPTG (Isopropyl-beta-D-thiogalactoside) is an inducer of the lac operon and is frequently used in conjunction with X-GAL to determine the lac phenotype of recombinant plasmids or phage. IPTG is also used to induce the expression of cloned genes that are under control of the lac operon. Supplied in one bottle containing 5 g. WebThermo 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. popcorn sweet and salty snack
