4-Methylumbelliferyl phosphate ,4-甲基伞形酮磷酸酯

A sensitive fluorogenic substrate for fluorometric and UV-spectrophotometric assays of phosphatases. It is used for the detection of C. perfringens because acid phosphatase is a highly specific indicator for C. perfringens.

4-Methylumbelliferyl Phosphate (4-MUP) is a fluorogenic substrate for phosphatases, including acid and alkaline phosphatases. It is converted to the fluorescent product 4-methylumbelliferone (4-MU), which has an emission maximum at 445-454 nm. The excitation maximum for 4-MU is pH-dependent: 330, 370, and 385 nm at pH 4.6, 7.4, and 10.4, respectively.
