ʻO kēia huahana he mea hoʻoulu i ka β-galactosidase a me ka β-galactosidase, ʻaʻole i hydrolyzed e β-galactoside, a he substrate no ka thiogalactosidase.Hoʻohana pinepine ʻia ka IPTG i nā hoʻokolohua cloning e koi ana i ka hoʻokomo ʻana i ka hana β-galactosidase.Hoʻohana pinepine ʻia me ka X-Gal a i ʻole Bluo-Gal no ka nānā ʻana i ka polū-keʻokeʻo o nā kolo bacteria recombinant i hiki ke Chemicalbook e hoʻoulu i ka ʻōlelo o ka operon lac ma E. coli.Hoʻopili ʻo IPTG i ka protein repressor lacI a hoʻololi i kona conformation e pale i ka pale ʻana i ka β-galactosidase-encoding gene lacZ.
