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[1]
• in acidic mammalian chitinase activity assay of human gastric juice[2]
• in chitinase assay in crystalline style extracts of Greenshell Mussels[3] and fungus Fusarium oxysporum.[4]

Actions biochimiques/physiologiques

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.[5]
