Fluorescent Phosphate Assay Kit

Cat.No. :

Kit-0689

Product Overview :

Fluorescent Phosphate Assay Kit is used for assessing phosphate over a wide range of concentrations.

Description :

Inorganic phosphate (Pi) is one of the most important ions in biological systems. It functions in a variety of roles.One of the most important roles is as a molecular switch, turning enzyme activity on and off through the mediation of the various protein kinases and phosphatases in biological systems. A highly sensitive assay is desired to monitor Pi in variety samples or monitor Pi changes during kinase and phosphatase reactions. The newly designed Fluorescent Phosphate Assay Kit provides a sensitive, easy, quick means of assessing phosphate over a wide range of concentrations. In the assay, inorganic phosphate reacted with maltose to produce glucose in the present of a special enzyme. The glucose is specifically oxidized to generate a product that reacts with the OxiRed probe to generate fluorescence (Ex/Em=535/587nm). The kit can be used to detect Pi in a variety of samples after reactions of ATPases, GTPases, 5"-nucleotidase, protein phosphatases, acid and alkaline phosphatases, and phosphorylase. Glucose background can be eliminated by doing a glucose control. Phosphate concentrations between 0.4 µM and 10 µM, with a lower limit of detection of approximately 40 pmol, can be directly determined.
