High purity IPTG  CAS: 367-93-1 Isopropyl-beta-D-thiogalactopyranoside High purity IPTG  CAS: 367-93-1 Isopropyl-beta-D-thiogalactopyranoside

High purity IPTG CAS: 367-93-1 Isopropyl-beta-D-thiogalactopyranoside

Isopropyl β-D-1-thiogalactopyranoside (IPTG) is a molecular biology reagent. This compound is a molecular mimic of allolactose, a lactose metabolite that triggers transcription of the lac operon, and it is therefore used to induce protein expression where the gene is under the control of the lac operator.

Usage: 

Isopropyl glucosinolates galactose glucoside (IPTG) is a kind of extremely strong inducer, not by bacteria metabolism and is very stable, so widely used by the laboratory. IPTG used to need to induce beta galactose glucoside enzyme activity of cloning experiments. It is often combined with X - Gal or Bluo - Gal to use, the blue and white screening of recombinant bacterial colonies, these colonies can induce the lac operon expressed in escherichia coli. IPTG combined with lacI inhibit protein and change its conformation and function, prevent beta galactose glucoside enzyme inhibition of lacZ genes encoding.
