Beschreibung

Anwendung

4-Methylumbelliferyl N-acetyl-β-D-glucosaminide has been used as a fluorogenic substrate in the acidic chitinase activity assay.[1] It has also been used to measure the total activity of β-N-acetylhexosaminidase (NAGase) in water sample filtrates.[2]

Biochem./physiol. Wirkung

4-Methylumbelliferyl-N-acetyl-β-D-glucosaminide (4-MUF-NAG) is a synthetic uncharged fluorogenic substrate for hexosaminidases.[3] It consists of chitin monomer (N-acetyl-β-D-glucosaminide) and 4-methylumbelliferone (7-hydroxy-4-methylcoumarin) (4-MUF). 4-MUF-NAG is used for the detection and estimation of fungal growth by measuring the β-N-acetylhexosaminidase (NAGase) activity.[4]
