Magenta-Gal (Highly Pure)

Magenta-Gal (Highly Pure) by Molecular Depot is a Magenta-Gal, an alternative to X-Gal that produces a red colour, a chromogenic β-galactosidase substrate that yields a magenta to red precipitate. The galactoside is cleaved by β-galactosidase to release an indoxyl, which oxidises and dimerises to an insoluble dye whose colour is set by the halogen substitution on the indole. It is used in blue-white and colour screening of bacterial colonies, in reporter gene staining and in histochemical β-galactosidase detection. Each unit contains 500 mg. MBP supplies Molecular Depot research reagents to research labs in the United States, Canada and worldwide.
