WebProduct Description. 5-Bromo-4-chloro-3-indolyl β-D-galactopyranoside is most commonly known as X-Gal. X-gal is a histochemical substrate for β-galactosidase which cleaves X-Gal to yield an insoluble blue precipitate. X-Gal is a mainstay in molecular biology cloning applications in which it is used to detect the activity of β-galactosidase.
