คำอธิบาย: Product Highlights Induces E.coli lac operon activity - suitable for cloning and protein expression procedures Dioxane free - does not disrupt normal cell function >99.6% purity - confirmed by HPLC Convenient - available as powder and stabilized stock solution Product Description Isopropyl-ß-D-thiogalactopyranoside (IPTG) is a chemical analogue of galactose, which cannot be hydrolyzed by the enzyme ß--Galactosidase. Hence, it induces the E. coli lac operon activity by binding and inhibiting the lac repressor without being degraded. Genes controlled by the lac or tac promotor/operator sequences are expressed to high levels in the presence of IPTG. IPTG is part of the Bioline Essentials range of products, which includes agaroses, buffers, PCR water and enhancers, antibiotic solutions, cloning reagents and protein digestion reagents.
