• Beschreibung: 4-Methylumbelliferyl-alpha-L-rhamnopyranoside is a fluorogenic substrate for alpha-L-rhamnosidase. 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-L-rhamnopyranosideas a substrate for measuring the alpha-L-rhamnosidase activity is used for detection of bacterial infection.
