4-Methylumbelliferyl-?-D-galactopyranoside (4-MU-?-Gal) is a fluorogenic substrate of ?-galactosidase.{33136,33137} In addition to its use in characterizing novel ?-galactosidases, 4-MU-?-Gal is used in assays to evaluate deficiency in ?-galactosidase activity related to Fabry disease.{33138} Hydrolysis of 4-MU-?-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.{27251}
