5-Bromo-4-chloro-3-indolyl b-L-fucopyranoside,X-b-L-Fucoside

5-Bromo-4-chloro-3-indolyl ?-L-fucopyranoside (X-Fuc) is a chromogenic substrate specifically designed for the identification and detection of fucosidase enzyme activity. Upon cleavage by fucosidase, it generates a blue-colored 5-Bromo-4-chloro-3-hydroxy-indole precipitate, which can be easily observed under a microscope or spectrophotometer. This feature makes X-Fuc an invaluable tool across various applications, such as biochemical analysis, histochemical staining, cell biology, and enzyme kinetic assays. By providing a fast, sensitive, and reliable readout for fucosidase activity, 5-Bromo-4-chloro-3-indolyl ?-L-fucopyranoside facilitates essential research in the understanding of biological processes and the development of therapeutic interventions.
