WebJun 1, 2024 · Isopropyl β- d -1-thiogalactopyranoside (IPTG), an analog of lactose, is the most popular chemical agent for induction of protein expression by Lac operons. This compound is not degradable by β-galactosidase. So, its concentration may be steady through experiment. WebDescription: This strain has mutations in the coding sequences for glutathione reductase ( gor) and thioredoxin reductase ( trxB). Also, it does not produce the lacY permease, which also permits tuning the concentration of the common inducer isopropyl β-D-1-thiogalactopyranoside (IPTG, see Section 3.5 ).
