Fluorescein diphosphate tetraammonium is a fluorescent dye, it can be used as a fluorogenic substrate and generats fluorescein as a fluorescent product.

体外研究:
Fluorescein diphosphate tetraammonium can be used as a fluorogenic substrate, and obtains luorescein as a fluorescent product.Fluorescein diphosphate tetraammonium (50 μM; room temperature) can be used as a substrate in vitro phosphatase assays.Guidelines (Following is our recommended protocol. This protocol only provides a guideline, and should be modified according to your specific needs).ELISA with capillary immunosensor (single-step ELISA):1. Put various concentrations of antigen in Tris buffer 1 containing 1% BSA into capillary immunosensor.2. Immobilize capture antibody and enzyme-linked antibody via capillary action, incubates for a preset time, and subsequently washing with 1 mL of 50 mM Tris buffer (pH 7.4) containing 0.14 M NaCl and 0.05% Tween 20 by using a syringe.3. Fluorescence is detected by introducing an excess volume (ca. 100 μL) of 20 μM FDP in 50 mM Tris buffer (pH 9) with an incubation time of 60 min.
