1. Field of the Invention
The present invention relates to a method of measuring pyrophosphate.
2. Description of the Related Art
As conventional techniques of measuring pyrophosphate enzymatically, there are known, for example, (i) a method involving using pyruvate orthophosphate dikinase and luciferase (Japanese Patent Application Laid-Open No. 2007-097471), (ii) a method involving using hypoxanthine phosphoribosyltransferase and xanthine dehydrogenase/oxidase (Japanese Patent Application Laid-Open No. 2003-174900), and (iii) a method involving using kinase, an enzyme for producing ATP from pyrophosphate, and dehydrogenase which requires NAD or NADP as a coenzyme (Japanese Patent Application Laid-Open No. 2006-187251).
