application

4-Methylumbelliferyl phosphate has been used as a substrate for alkaline phosphatase in the peptide-binding assay.[1] It has also been used as a fluorogenic substrate in enzyme-linked immunosorbent assay (ELISA).[2][3]

Biochem/physiol Actions

4-Methylumbelliferyl phosphate serves as a fluorogenic substrate for calmodulin-dependent protein phosphatase and in kinetic studies of alkaline phosphatase. It is a substrate for alkaline phosphatase[4] in enzyme-linked immunosorbent assay (ELISA) procedures. 4-Methylumbelliferyl phosphate is seven times more sensitive than phenolphthalein monophosphate and 8-13 times more sensitive than with p-nitrophenyl phosphate when used in enzyme immunoassays for the detection of antibodies to human immunodeficiency viruses.

Substrates

Fluorogenic substrate for phosphatases.
