IPTG (Isopropyl-β-D-thiogalactopyranoside) is a galactose analogue not recognized by β-galactosidase. It is an inducer of the operon in E. coli.
At a 1 mM concentration, IPTG induces β-glactosidase gene expression allowing the selection of Lac+ recombinant bacteria in X-Gal containing medium.
IPTG is water soluble. Store at -20°C.
