IPTG

PTG (Isopropyl B-D-1-thiogalactopyranoside), 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. • Induces E.coli lac operon activity - suitable for cloning and protein expression procedures. • Dioxane free - does not disrupt normal cell function. • >99.6% purity - confirmed by HPLC. • Convenient - available as powder and stabilized stock solution.
