IPTG
IPTG (isopropyl-β-thiogalactoside) is an analogue of allolactose that binds specifically to the repressor protein of the lac operon and induces expression of β-galactosidase in Escherichia coli.
IPTG is a commonly used reagent in cloning procedures that require induction of b-galactosidase activity and is used in conjunction with X-Gal in blue-white color selection of recombinant bacterial colonies.
The final concentration typically used in indicator plates is 0.2 mM.
- Presentation: Crystalline, Dioxane-free,β-Galactosidase inducer
- Soluble in methanol and water (50 mg/mL - clear, colorless solution)
- Storage temperature: -20°C, desiccate
IPTG (isopropyl-β-thiogalactoside) is an analogue of allolactose that binds specifically to the repressor protein of the lac operon and induces expression of β-galactosidase in Escherichia coli. The compound is widely used with X-Gal (5-Bromo-4- chloro-3-indolyl- beta-D-galactopyranoside, MP catalog number 150001) plates to screen for blue and white colonies. The lac operon system and IPTG have been used in multiple cloning experiments and cellular systems to study gene activity. The final concentration typically used in indicator plates is 0,2 mM.
