4-Methylumbelliferyl-alpha-L-Fucopyranoside

Description: 4-Methylumbelliferyl-alpha-L-fucopyranoside serves as a fluorogenic substrate for alpha-L-fucosidase, releasing 4-methylumbelliferone (4-?U) upon enzymatic cleavage by the enzyme. The fluorescence of 4-?U, with excitation/emission maxima at 350/440 nm, respectively, allows for the quantification of alpha-L-fucosidase activity.
