4-Methylumbelliferyl-α-D-Glucopyranoside (4-Methylumbelliferyl-α-D-Glucose) is a fluorescent substrate for α-glucosidase, which releases the fluorescent moiety 4-methylumbelliferyl (4-MU) upon cleavage. 4-MU has pH-dependent fluorescence excitation activity, with excitation wavelengths of 320 nm at low pH (1.97-6.72) and 360 nm at high pH (7.12-10.3), respectively.
