CF-MUP, sodium salt *Superior alternative to MUP*Cat # 11628 Storage F/D/L (see storage codes below) Unit Size 10 mg Ex (nm) 360 Em (nm) 450 MW 352.55 Solvent Water Although MUP is widely used for detecting phosphatases in solution it is not well suited for living cell or continuous assays since MU (4-methylumbelliferone), the enzymatic product, which only develops maximum fluorescence at pH value of >10. Thus it is also difficult to use MUP for the detection of phosphatases that have acidic optimal pH range such as acid phosphatases. AAT Bioquest is pleased to offer CF-MUP Plus that is developed to address this pH limitation associated with MUP substrates. CF-MU exhibits maximum fluorescence above pH 5.0, thus CF-MUP substrate can be well used for continuous phosphatase assays. It can also be used for the assays that require acidic pH such as acid phosphatases and some protein phosphatases.
