WebThe blue-white screening tests for interruption of the beta-galactosidase coding sequence by introduction of another piece of DNA (your insert). Most inserts will disrupt beta-gal expression... WebIPTG. IPTG is an analog of galactose that is nonmetabolizable and inactivates the lac repressor to induce synthesis of β-galactosidase in E. coli. The expression of cloned genes under the control of the lac operon is induced by IPTG. IPTG is often used in the induction of recombinant proteins, is a substrate for thigalactoside transacetylase ...

WebProduct Description. Bluo-Gal is used as an alternative to X-Gal, and produces a darker blue color. Bluo-Gal is hydrolyzed by β-galactosidase to produce a blue precipitate. This precipitate is insoluble in alcohol and xylenes, thus making it suitable for immunoblotting and immunocytochemical assays. Bacterial colonies containing active β ... WebWhat concentrations do you typically recommend for X-gal and IPTG for blue/white screening? In plates, we recommend 50 µg/mL X-gal and 1 mM IPTG (0.24 mg/mL). When spreading directly onto agar plates, we recommend 40–50 µl of 40 mg/mL X-gal (2% stock) in dimethylformamide and 30–40 µl of 100 mM IPTG on top of the agar.
