6-Fluoro-3-indoxyl-β-D-galactopyranoside (Highly Pure) by Molecular Depot is a 6-fluoro-3-indolyl β-D-galactopyranoside, a chromogenic substrate for β-galactosidase. Cleavage releases a fluorinated indoxyl that oxidises and dimerises into an insoluble indigo dye at the point the enzyme acted, and the fluorine shifts the shade of the deposit. It is used to detect β-galactosidase activity in histochemical staining, colony screening and reporter gene assays. Each unit contains 50 mg. MBP supplies Molecular Depot carbohydrate reagents to research labs in the United States, Canada and worldwide.
