Cov khoom no yog ib qho inducer ntawm β-galactosidase thiab β-galactosidase, tsis hydrolyzed los ntawm β-galactoside, thiab yog ib tug substrate rau thiogalactosidase.IPTG feem ntau yog siv rau hauv kev sim cloning uas yuav tsum tau induction ntawm β-galactosidase kev ua.Nws feem ntau yog siv ua ke nrog X-Gal lossis Bluo-Gal rau kev tshuaj ntsuam xiav-dawb ntawm cov kab mob sib xyaw ua ke uas tuaj yeem ua tshuaj rau induce qhia ntawm lac operon hauv E. coli.IPTG khi rau lacI repressor protein thiab hloov nws qhov kev sib haum xeeb los tiv thaiv kev cuam tshuam ntawm β-galactosidase-encoding gene lacZ.
