Application

5-Bromo-4-chloro-3-indolyl β-D-galactopyranoside has been used to confirm transduction of Caki-2/LacZ clones.[1] It has also been used in blue-white selection of transformants.[2]
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.

Preparation Note

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.
