4-Methylumbelliferyl b-D-xylobioside

CAS: 158962-91-5

4-Methylumbelliferyl beta-D-xylobioside is a fluorogenic substrate for xylanase. 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 beta-D-xylobiosideas a substrate for measuring the xylanase activity is used for detecting bacterial infection and gut microbiome analysis.
