Fluoro Phosphate
$235.00
Introduction
Phosphorus is essential for multiple and diverse biological functions, including cellular signal transduction, mineral meatbolism, and energy exchange. Elevated levels of serum phosphate may be associated with a higher risk of death and adverse cardiovascular outcomes in people with prior myocardial infarction, and is the subject of large amount of research.
Key Benefits
- Quantitation of phosphate anion in blood, plasma and serum samples.
- Sensitive – can detect upto 200nM phosphate
- Easy to use – Fluorescence (ex/em 535/585nm or Absorbance readout @ 570nm)

Cell Technology’s Phosphate detection kit provides a simple, one-step fluorimetric or colorimetric method for determination of phosphate in serum and plasma samples. The assay is based on an enzyme-coupled reaction that detects inorganic phosphate. The substrate is converted to Hydrogen peroxide in presence of inorganic phosphate in a coupled enzymatic reaction. The Hydrogen Peroxide then reacts with the detection reagent in a 1:1 stoichiometry in presence of Horse Radish Peroxidase to produce the stable fluorescent product.
