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. Application 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.
