产品介绍

Isopropyl beta-D-thiogalactoside(IPTG)

Isopropyl beta-D-thiogalactoside(IPTG)是异乳糖模拟物,能够引起乳糖操纵子的转录过程,因此能够诱导乳糖操纵子下游基因对应蛋白的表达。

Background:
IPTG 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.

IPTG uptake by E. coli can be independent of the action of lactose permease, since other transport pathways are also involved. At low concentration, IPTG enters cells through lactose permease, but at high concentrations (typically used for protein induction), IPTG can enter the cells independently of lactose permease[1].
