AdipoGen 4-MUP
Chemical. CAS 22919-26-2. Formula C10H7Na2O6P. MW 300.11. 4-Methylumbelliferyl phosphate 4-MUP is a fluorogenic substrate for phosphatases mainly alkaline. 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. Therefore, this phosphatase substrate is not well suited for living cell or continuous assays since 4-MU only develops maximum fluorescence at a pH value of >10. Spectral data lambdaex=319nm lambdaem=384nm pH 9.0. lambdaex=360nm lambdaem=449nm for reaction product.
