4-Methylumbelliferyl N-acetyl-a-D-neuraminic acid ammonium

CAS: 206442-98-0

4-Methylumbelliferyl N-acetyl-alpha-D-neuraminic acid ammonium is a fluorogenic substrate for neuraminidase. 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 N-acetyl-alpha-D-neuraminic acid ammoniumas a substrate for measuring the neuraminidase activity is used for detecting the glycoproteins on the surface of influenza A and B viruses, as well as for sialidosis diagnosis.
