4-Methylumbelliferyl phosphate (4-MUP) 是一种碱性磷酸酶的荧光底物。
4-Methylumbelliferyl phosphate monoester previously described as one of a series of 4-methylumbelliferone conjugates is later found to be the PlP2-pyrophosphate diester and is not hydrolysed by serum phosphomonoesterases . 4-Methylumbelliferyl phosphate has a significant advantage over currently available substrates in that its useful concentration range extends to about 0.1 μM.
If the concentration of 4-Methylumbelliferyl phosphate is held constant and the pH is varied, the activity of the enzyme passes through a maximum.
