Biological Activity: X-GAL (BCIG) is a widely used chromogenic β-galactosidase substrate. X-GAL is a colorless compound until cleaved by β-galactosidase, at which point X-GAL turns to an insoluble and detectable blue compound, making X-GAL particularly useful in techniques such as blue-white screening for cloning in bacteria. X-GAL can also be used for detection of β-galactosidase activity[1][2].
