WebIPTG (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. Product Highlights WebThe DE3 designation means the strains contain the lambda DE3 lysogen that carries the gene for T7 RNA polymerase under control of the lacUV5 promoter. This promoter is regulated by the endogenous E. coli lacI protein and is induced with IPTG. IPTG is required to induce expression of the T7 RNA polymerase.
