Weitere Details:: 5-Bromo-6-chloro-3-indoxyl-beta-D-galactopyranoside is a chromogenic substrate for beta-D-galactosidase, yielding a magenta precipitate and contained in a chromogenic culture media. It is an indolyl carbohydrate that is the alpha-D-mannoside of indoxyl, in which the indole moiety is substituted at positions 4 and 5 by chlorine and bromine, respectively. When Magenta-Gal is hydrolyzed by β-galactosidase, the resulting product will form a red precipitate. Lac+ colonies grown in the presence of Red-Gal turn an intense red color, allowing for easy differentiation between lac+ and lac- colonies. Synonyms: Red b-D-gal; Magenta gal CAS No: 93863-88-8 Molecular Formula: C14H15BrClNO6 Molecular Weight: 408.63 Appearance: White to off-white powder Purity: ≥98% (HPLC) FT-IR Spectrum: Conforms to reference Solubility: Methanol Storage and Stability: May be stored at RT for short-term only. Long-term storage is recommended at -20°C. For maximum recovery of product, centrifuge the original vial prior to removing the cap.
