Meridian Bioscience (Bioline)


IPTG (Isopropyl ß-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
