4-Methylumbelliferyl α-D-xylopyranoside

CAS: 1643953-00-7

4-Methylumbelliferyl alpha-D-xylopyranoside is a fluorogenic substrate for alpha-xylosidase. After enzymatic cleaveage, free 4-methylumbelliferone (also known as hymecromone) is released, exhibiting blue fluorescence upon excitation with UV light. The strongest fluorescence of 4-methylumbelliferone requires deprotonation of the hydroxyl group (thus requires alkaline pH), with a maximal fluorescence intensity obtained with excitation at 350 to 370 nm and emission at 440 to 470 nm. The use of 4-methylumbelliferyl alpha-D-xylopyranosideas a substrate for measuring the alpha-xylosidase activity is used for oligosaccharidosis monitoring and other lysosomal storage disorder diagnosis.
