X-Gal
X-Gal (5-bromo-4-chloro-3-indolyl-beta-D-galactoside)
X-Gal (5-Bromo-4-Chloro-3-Indolyl-beta-D-Galactoside) is a chromogenic substrate for β-galactosidase that yields a blue precipitate upon hydrolysis.
Overview
- A histochemical substrate for beta-galactosidase that yields a blue precipitate upon hydrolysis
- Used with IPTG (9030) in media to select recombinants using blue/white colony screening
Purity
- Biological activity as the substrate for beta-galactosidase was examined
- Purity was examined by TLC analysis
Storage
–20°C
Properties
Molecular weight: 408.6
Form
White powder
