IPTG
>99.0% Purity confirmed by HPLC & Dioxane free
IPTG (Isopropyl B-D-thiogalactopyranoside), Dioxane-Free is an analogue of allolactose that binds specifically to the repressor protein of theĀ lacĀ operon and induces expression of Ī²-galactosidase inĀ Escherichia coli.Ā Unlike allolactose, IPTG is not a substrate for b-galactosidase, as the carbon-sulfur bond cannot be cleaved by the enzyme, so its concentration remains constant. The compound is widely used with X-Gal plates to screen for blue/white selection of recombinant bacteria.
