Molecular Biology Grade IPTG
By MP BiomedicalsIPTG (Isopropyl-β-D-thiogalactopyranoside) is a galactose analog not recognized by β-galactosidase. It is an inducer of the operon in E. coli. At a 1 mM concentration, IPTG induces β-galactosidase gene expression allowing the selection of Lac+ recombinant bacteria in X-Gal containing medium. IPTG is water soluble.
