异丙基 β-D-1-硫代半乳糖吡喃糖苷
A chemical analogue of galactose which cannot be hydrolysed by the enzyme ß-galactosidase. IPTG is an inducer for activity of the E.Coli lac operon which acts by binding and inhibiting the lac repressor. Genes controlled by the lac promoter/operator sequence are expressed to high levels in the presence of IPTG. Essentially dioxane free.
