Reactivity data
Product details
Pyrophosphate assay kit ab234040 is used to quantify Pyrophosphate (abbreviated as PPi). Pyrophosphate, also called PPi and diphosphate, consists of two phosphate groups connected to each other through an oxygen atom.
Pyrophosphate assay principle
In the pyrophosphate assay, Pyruvate phosphate dikinase acts on pyrophosphate, in the presence of AMP and phosphoenolpyruvate, to produce pyruvate. Pyruvate is then acted on by pyruvate oxidase producing hydrogen peroxide as a product. The hydrogen peroxide reacts with a probe via a peroxidase to generate color (spectrophotometry at λ= 570 nm) and fluorescence (Ex/Em = 535/587 nm). Readout is on a colorimetric or fluorometric plate reader.
Monomeric inorganic phosphate (Pi) does not interfere with the assay.

Biological function summary
Inorganic pyrophosphate plays a critical part in bone mineralization and the regulation of calcium and phosphate metabolism. It influences the bone matrix's deposition by calcifying or inhibiting mineralization depending on the balance with phosphates. Within the extracellular matrix pyrophosphate remains associated with proteins such as alkaline phosphatase which converts PPi to phosphate promoting mineralization. Pyrophosphate's activity shows strong relevance in maintaining extracellular fluid stability preventing excessive calcification.
Pathways
The involvement of inorganic pyrophosphate occurs prominently in the regulation of the ATP metabolism pathway and cartilage formation. It is closely related to the enzyme family of pyrophosphatases which include both soluble inorganic pyrophosphatase and membrane-integrated soluble pyrophosphatases. These enzymes orchestrate converting pyrophosphate into orthophosphate ions feeding into the pathways that regulate energy homeostasis and biomineralization. Interaction with proteins like ENPP1 and TNAP highlight its role within the broader context of nucleic acid synthesis and tissue calcification.
