Iptg, Dioxane-Free, Induce The Expression Of Genes Under The Control Of Lac Operon In Cloning And Protein Expression Procedures, Each

Details:

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 . It is used in conjunction with x-gal (#r0941) to determine the lac phenotype in blue/white colony screening.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.
