일반 설명
Isopropyl β-D-Thiogalactopyranoside (IPTG) is a molecular biology reagent used to induce gene expression in bacterial systems. It mimics lactose, binding to the lac repressor protein, leading to gene activation. IPTG is crucial for studying gene regulation, protein expression, and recombinant protein production, providing valuable insights into cellular and molecular biology research.
애플리케이션
IPTG has been used:
- in the induction of protein expression in Lactobacillus reuteri GroEL and mutants
- in the induction of protein expression in Escherichia coli
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. IPTG functions by binding to the lacI repressor and altering its conformation, which prevents the repression of the β-galactosidase coding gene lacZ.
생화학적/생리학적 작용
IPTG is a non-metabolizable analog of allolactose. It acts as an inducer that regulates the transcriptional activity of the lac promoter, a promoter that is used for the expression of the protein in E.coli.
기타 정보
Non-metabolizable galactose analog.

재구성
A stock solution (0.1 M) is prepared by dissolving IPTG in water with subsequent sterile filtration of the solution. The final concentration of IPTG in indicator plates should be 0.2 mM.
