Detailed Photos

 

Isopropyl β-D 1thiogalactopyranoside (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. IPTG, unlike allolactose, is not hydrolyzable by βgalactosidase, its concentration, therefore, remains constant in an experiment. For induction, a sterile, filtered 1 M solution of IPTG is typically added by 1:1000 dilution into a logarithmically growing bacterial culture, however, the different final concentration of IPTG may also be used.
 
Function
 
IPTG is often used for induction β- Cloning experiment of galactosidase activity. It is often used in combination with X-gal or bluo gal for blue-white screening of recombinant bacterial colonies. These colonies can be chemically book to induce the expression of lac operon in E. coli. IPTG binds to lacI repressor protein and changes its conformation to prevent β- Inhibition of galactosidase coding gene lacZ.
