Background:

4-Methylumbelliferyl-α-D-galactopyranoside (4-MU-α-Gal) is a fluorogenic substrate of α-galactosidase. In addition to its use in characterizing novel α-galactosidases, 4-MU-α-Gal is used in assays to evaluate deficiency in α-galactosidase activity related to Fabry disease. Hydrolysis of 4-MU-α-Gal releases the fluorescent product 4-MU, which has an emission maximum at 445-454 nm. The excitation maximum for 4-MU is pH-dependent: 330, 370, and 385 nm at pH 4.6, 7.4, and 10.4, respectively.
