Fluorescein diphosphate tetraammonium salt

Description: Fluorescein diphosphate tetraammonium salt is a colorless and nonfluorescent substrate for alkaline phosphatases. The sequential alkaline phosphatase mediated hydrolysis of its two phosphate substituents yielding weakly fluorescent fluorescein monophosphate followed by strongly fluorescent fluorescein. Target: Others. Smiles: O=C1OC2(C3=C1C=CC=C3)C4=CC=C(C=C4OC5=CC(OP([O-])([O-])=O)=CC=C52)OP([O-])([O-])=O.[NH4+].[NH4+].[NH4+].[NH4+].
