Magenta-gal is used as an alternative to X-gal that produces a red color. Magenta-Gal is hydrolyzed by β-galactosidase to produce a red precipitate. This precipitate is insoluble in alcohol and xylenes, thus making it suitable for immunoblotting and immunocytochemical assays. Bacterial…

Chromogenic substrate for the β-Galactosidase. Used in histochemistry for the localization of the enzyme activity in mammalian tissues. Produces an insoluble magenta chromophore. An alternative to X-Gal.
