Application

4-Methylumbelliferyl α-D-galactopyranoside has been used as an artificial substrate to assay α-galactosidase-A activity.

Biochem/physiol Actions

4-Methylumbelliferyl α-D-galactopyranoside is a fluorogenic substrate for α-galactosidase-A. The enzyme converts the substrate to form a blue fluorescent product, methylumbelliferyl. The fluorescence is measured spectrophotometrically.

Preparation Note

4-Methylumbelliferyl α-D-galactopyranoside is soluble in water (50 mg/ml), yielding a clear, colorless to faint yellow solution with the application of heat.

Alpha-galactosidase A hydrolyzes the terminal alpha-galactosyl moieties from glycolipids and glycoproteins in lysosomes. Mutations in alpha-galactosidase cause lysosomal accumulation of the glycosphingolipid, globotriaosylceramide, which leads to Fabry disease.

An enzyme-linked immunosorbent assay (ELISA) for prostate specific antigen (PSA) detection in human serum was developed based on the potentiometric detection of 6,8-difluoro-4-methylumbelliferone (DiFMU). The assays were carried out in anti-human PSA capture antibody modified microtiter plates (150 microL volume).
