4-Methylumbelliferyl-α- D-galactopyranoside is a fluorogenic substrate for α-gal A (α-galactosidase), yielding a blue fluorescent solution upon cleavage. 4-Methylumbelliferyl-α- D-galactopyranoside is potentially useful in differentiating species within the family of Enterobacteriaceae and in the localization of α-galactosidase in plants.
