一般描述
Isopropyl thiogalactose (IPTG) is a sugar derivative widely used for the induction of the expression of recombinant proteins in E. coli. This expression system requires that the gene of interest is cloned in plasmids containing the Lac promoter. IPTG Ready Made is a 0.2 μm filter sterilized solution of 200 mM IPTG. This reagent remains liquid at its storage temperature (-20 °C), thus avoiding freeze-thaw cycles and providing a user-friendly solution.
应用
Isopropyl β-D-thiogalactopyranoside solution is:
生化/生理作用
Isopropyl β-D-thiogalactopyranoside binds to the lac repressor and releases the tetrameric repressor from the lac operator in an allosteric manner. This binding allows the transcription of genes in the lac operon, such as the gene coding for β--galactosidase. The β-galactosidase gene is transcribed and monosaccharides are the product. Since Isopropyl β-D-thiogalactopyranoside cannot be metabolized by E. coli its concentration remains constant. Therefore, it is not a variable in the experiment.[4]

The role of the Escherichia coli lacY gene product (the lactose permease) in the induction of isopropyl-beta-D-thiogalactopyranoside (IPTG) inducible promoters was studied in E. coli and P. fluorescens. This was done by comparing strains containing a lacIPOZYA chromosomal insert with
