X-α-Gal is a 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 Lactobacilli species.
