4-METHYLUMBELLIFERYL-ALPHA-D-GALACTOPYRANOSIDE Usage And Synthesis

Chemical Properties

Off-White Solid

Uses

A fluorogenic substrate in the assay of a-galactosidase

Uses

A fluorogenic substrate in the assay of α-galactosidase.

Uses

FFluorescent substrate for ?-galactosidase activity in cell extracts, lysosomes and human blood serum. The lower pKa of the hydrolysis product, allows its detection at phisiological pH5.

Definition

ChEBI: An alpha-D-galactoside having a 4-methylumbelliferyl substituent at the anomeric position
