X-GAL is a chromogenic permeable substrate to detect β-galactosidase activity, generating an intense blue coloration that is easily distinguishable from the background.. The enzyme hydrolyzes X-GAL releasing galactose and 5-Bromo-4-Chloro-3-hydroxyindole. Indole compound produced is dimerized and oxidized generating an insoluble dark blue product.
