IPTG (Isopropyl-β-D-thiogalactopyranoside)
Isopropyl-D-thiogalactopyranoside (IPTG) is a chemical analogue of galactose, which cannot be hydrolyzed by the enzyme --Galactosidase. Hence, it induces the E. coli lac operon activity by binding and inhibiting the lac repressor without being degraded.

  • Blue/White Color Screening
  • Induction of Lac Operon for Protein Expression
  • Genes Controlled by the Lac to Tac Promoter/Operator Sequences are Expressed to High Levels in the Presence of IPTG

Genes controlled by the lac or tac promotor/operator sequences are expressed to high levels in the presence of IPTG. Features include induces E. coli lac operon activity, >99.6% by HPLC, and available as powder and stabilized stock solution. IPTG powder can be stored for 12 months at -20°C. Shipped on dry ice or blue ice.
