IPTG, Isopropyl-beta-D-Thiogalactopyranoside

IPTG, Dioxane-Free (isopropyl-β-d-thiogalactopyranoside), is an inducer of β-galactosidase activity in many bacteria. Functioning as a lac analog, IPTG induces β-galactosidase activity by binding to and inhibiting the lac repressor. This product is used to differentiate recombinants from nonrecombinants in cloning strategies using vectors containing the lacZ or lacZ α-peptide gene.Store at -20℃ Solubility Soluble in water and methanol pH 5% in Water 5.0-7.0 Assay by HPLC 98-101% w/w (on anhydrous basis)
