The preferred use of IPTG (isopropyl Î²-D-thiogalactopyranoside) in order to induce lacZYA operon. Introduction: IPTG is a chemical reagent with a similar structure to lactose. It is used in the induction of transcription in lac operon and further induction of protein expression at high levels. Catabolic repression is a phenomenon in which repression of lac operon occurs because glucose acts as a preferred carbon source instead of lactose and thus, glucose directly induces transcription.
