Description

X-Gal (5-bromo-4-chloro-3-indolyl-β-D-galactoside) is a histochemical substrate for β-galactosidase. This substrate yields a blue precipitate upon hydrolysis, making it suitable for use in immunoblotting or immunocytochemical assays. Bacteria containing active β-galactosidase produce blue colonies when grown on plates containing X-Gal. X-Gal is supplied as white crystals and is soluble in dimethylformamide.

Primary applications

Blue-white screening—detect functional β-galactosidase (reporter gene expression)
Histochemical detection of β-galactosidase activity in fixed tissues
X-gal overlay assay
