Description:
X-α-Gal;
5-Bromo-4-chloro-3-indoxyl-α-D-galactopyranoside;
X-α-D-Galactoside
MOLECULAR BIOLOGY GRADE
C14H15BrCNO6
MW: 408.64 g/mol
Chromogenic substrate for α-galactosidase yielding a blue precipitate. X-α-Gal is used for detecting two-hybrid interactions directly on the culture media. This substrate eliminates the need for β-galactosidase liquid and filter-lift assays in two-hybrid analysis.
Used for species differentiation within the family Enterobacteriaceae and differentiation of Bifidobacteria species from Lactobacillus species.
Store at -15°C. Protect from light.
