WebDec 2, 2024 · To screen bacterial colonies, the chromogenic substrate X-Gal and the gratuitous inducer IPTG are mixed with suitable dilution of a culture, combined with … 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. If β-galactosidase is produced, X-gal is … See more

WebFeb 18, 2024 · In general, 100 μL 10 −6 diluted bacterial solution was plated on LB agar plates containing IPTG and 5-Bromo-4-chloro-3-indolyl β-D-galactopyranoside (X-gal) and grown overnight. Efficiency of allelic replacement was calculated by taking the ratio of the number of white colonies to the total number of colonies on plates.
