Isopropyl-β-D-thiogalaktopyranosid
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.
