WebIPTG (also known as Isopropyl-β-D-Thiogalactopyranoside) is a molecular biology reagent that functions as an inducer of galactosidase activity by binding to and inhibiting the … WebIsopropyl-β-D-thiogalactoside (IPTG) is commonly used in cloning procedures that require induction of β-galactosidase activity. It is used in conjunction with X-Gal or Bluo-Gal in blue-white selection of recombinant bacterial colonies that induce expression of the lac operon in Escherichia coli.It has been used for the expression of recombinant genes in E. coli.

WebIPTG (isopropylthio-β-galactoside) is an inducer of β-galactosidase activity in bacteria and is suitable for use with X-gal or bluo-gal to detect lac gene activity during cloning. Life … WebOn the other hand, the induction of B-galactosidase responded differently when different carbohydrates were added (Fig. 2). The control culture containing only the IPTG and glycerol showed an early rapid induction, which eventually levelled. The culture in which galactose was added, at first, only had a slight decrease in induction. WebIPTG is a reagent which mimics the structure of allolactose, and can therefore bind to the lac repressor and prevent it from inhibiting gene expression. Once enough IPTG is added, the T7 gene is normally transcribed and so transcription of the gene of interest downstream of the T7 promoter also begins. [6] lithium iron phosphate material
