Induction of lac operon for protein expression
Genes controlled by the lac or tac promoter/operator sequences are expressed to high levels in the presence of IPTG
Isopropyl-ß-D-thiogalactopyranoside (IPTG) is a chemical analogue of galactose, which cannot be hydrolysed 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 promoter/operator sequences are expressed to high levels in the presence of IPTG.
IPTG Solution is part of our Essentials range of products, which includes agaroses, buffers, PCR water and enhancers, antibiotic solutions, cloning reagents and protein digestion reagents.
