WebApr 11, 2024 · Frequently used inducers are small molecules such as arabinose or IPTG. However, due to interference of arabinose with catabolite repression ( Miyada et al., 1984) and the relatively high price of IPTG, their use is often economically impractical for large-scale production of bulk products. Isopropyl β-D-1-thiogalactopyranoside (IPTG) is used along with X-gal for blue-white screening. IPTG is a non-metabolizable analog of galactose that induces the expression of lacZ gene. It should be noted that IPTG is not a substrate for β-galactosidase but only an inducer. See more Blue-white screening is a rapid and efficient technique for the identification of recombinant bacteria. It relies on the activity of β-galactosidase, an enzyme occurring … See more The presence of lactose in the surrounding environment triggers the lacZ operon in E. coli. The operon activity results in the production of β-galactoisdase enzyme … See more For screening the clones containing recombinant DNA, a chromogenic substrate known as X-gal is added to the agar plate.
