Description

Application

4-Methylumbelliferyl β-D-N,N′-diacetylchitobioside hydrate has been used as a fluorogenic substrate:

• in chitinase enzyme assay of bronchoalveolar lavage samples
• in acidic mammalian chitinase activity assay of human gastric juice
• in chitinase assay in crystalline style extracts of Greenshell Mussels and fungus Fusarium oxysporum.

Biochem/physiol Actions

4-Methylumbelliferyl β-D-N,N′-diacetylchitobioside hydrate (MUF-diNAG) is an analog of chitin. It is a fluorogenic substrate for chitin depolymerase and its breakdown results in methylumbelliferone, a fluorescent product.
