Bluo-Gal (Highly Pure) by Molecular Depot is a Bluo-Gal, a halogenated indolyl galactoside that gives a darker blue product than X-Gal. Bluo-Gal carries a bromine where X-Gal carries both a bromine and a chlorine, and the different halogenation gives an indigo precipitate that is denser and darker. It is used as a chromogenic substrate for β-galactosidase in blue-white colony screening, in lacZ reporter staining and in histochemistry. Each unit contains 50 mg. MBP supplies Molecular Depot research reagents to research labs in the United States, Canada and worldwide.
