X-α-Gal

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.X-α-Gal is commonly used for species differentiation within the familyEnterobacteriaceaeand differentiation ofBifidobacteriaspecies fromLactobacillispecies.Product SpecificationsX-α-Gal5-Bromo-4-chloro-3-indoxyl-α-D-galactopyranosideX-α-D-GalactosideMOLECULAR BIOLOGY GRADEFormula: C14H15BrClNO6MW: 408.64 g/molPubChem Chemical ID:10173103
