General description

4-Methylumbelliferyl phosphate (4-MUP) is a substrate for alkaline phosphatase which forms the soluble fluorescent substance methylumbelliferone. 4-MUP Liquid Substrate System combines 4-MUP and buffer in a ready-to-use reagent.

Application

4-Methylumbelliferyl phosphate (4-MUP) Liquid Substrate System has been used as a fluorescent substrate for alkaline phosphate in enzyme linked immunosorbent assay (ELISA). It has also been used in secreted embryonic alkaline phosphatase (SEAP) activity assay.

Analysis Note

4-MUP fluorescence can be measured with excitation at 360 nm and emission at 440 nm. The fluorescent end product may also be observed using a UV light source.
