5-Bromo-4-chloro-3-indolyl beta-D-galactopyranoside, >=98%

Descriptions

Application

X-Gal is a chromogenic substrate for β-galactosidase that produces a rich blue color that can easily be detected visually over background. X-Gal is the substrate of choice for blue-white selection of recombinant bacterial colonies with the lac⁺ genotype.

5-Bromo-4-chloro-3-indolyl ?-D-galactopyranoside has been used to confirm transduction of Caki-2/LacZ clones. It has also been used in blue-white selection of transformants.

Packaging

10, 100, 500 mg in poly bottle

Reconstitution

A stock solution (100?mg/ml) is prepared by dissolving X-Gal in dimethylformamide and should be stored at −20?°C and protected from light. Sterilization is not required.
