You searched for: Fluorescein diphosphate tetraammonium salt (FDP)

Supplier: AAT BIOQUEST

Upon interaction with phosphatases the colourless and non-fluorescent FDP is hydrolysed to highly fluorescent fluorescein, which exhibits excellent spectral properties that match the optimal detection window of most fluorescence instruments that are equipped with the Argon laser excitation.

FDP (fluorescein diphosphate, tetraammonium salt, high purity) is the most sensitive fluorogenic alkaline phosphatase substrate. It is also an excellent substrate for protein tyrosine phosphatase (PTPase) and thus the substrate of choice in the high throughput screening (HTS) for PTPase inhibitor. FDP itself is colorless, but the end product of the enzymatic reaction is the green fluorescent dye fluorescein.
