Magenta-Gal is used as an alternative to X-Gal, and 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 colonies containing active β-galactosidase produce red colonies when grown on plates containing Magenta-Gal.
Magenta-Gal is commonly used in conjunction with IPTG (GoldBIo #I2481) for red/white screening.
