Le mveliso i-inducer ye-β-galactosidase kunye ne-β-galactosidase, kungekhona i-hydrolyzed nge-β-galactoside, kwaye i-substrate ye-thiogalactosidase.I-IPTG isetyenziswa ngokuqhelekileyo kwiimvavanyo ze-cloning ezifuna ukuqaliswa komsebenzi we-β-galactosidase.Ihlala isetyenziselwa ukudibanisa ne-X-Gal okanye i-Bluo-Gal yokuhlola iblue-white ye-recombinant bacterial colonies enokuthi ibe yi-Chemicalbook ukuze ikhuthaze ukubonakaliswa kwe-lac operon kwi-E. coli.I-IPTG ibophelela kwiprotheni ye-lacI ye-repressor kwaye iguqule ukuhambelana kwayo ukukhusela ukuvinjelwa kwe-β-galactosidase-encoding gene lacZ.
