QuantiFluoTM ALP Reagent is a stable 4-methylumbelliferyl phosphate (MUP) liquid substrate reagent formulated for detecting alkaline phosphatase ALP, e.g. in ELISA. This single reagent produces a highly fluorescent product (ex/em = 360/450 nm) when dephosphorylated by ALP. The fluorescent product can also be visualized under a UV light. This product is for Research Use only and is not intended for diagnostic purposes.
