4-甲基傘形酮-b-D-葡萄糖醛酸苷,4-Methylumbelliferyl b-D-glucuronide dihydrate (MUG)

4-Methylumbelliferyl beta-D-glucuronide (MUG) is commonly used as a substrate for detecting beta;-glucuronidase. MUG is used for identifying E. coli contamination in food, drinkingwater, clinical samples and for rapid bacterial identification in blood cultures. It is recommended in international normatives (ISO, DIN) as a fluorogenic substrate for detection of E. coli. MUG is also a tool assaying the glucuronidase gene in plants.

4-Methylumbelliferyl-β-D-glucuronide hydrate is a fluorogenic substrat (λex=362 nm , λem=445 nm).
