Bioluminescence reagent and method for quantitative determination of adenosine phosphate ester using the reagent

摘要

There is provided a bioluminescence reagent comprising at least pyruvate orthophosphate dikinase, phosphoenolpyruvic acid, pyrophosphoric acid, magnesium ion or another metallic ions, luciferin and luciferase, which reagent is such that the amount of luminescence is maintained in a high level and moreover stably without decaying for a long time in a bioluminescence reaction, and there is provided a method for quantitatively determining an adenosine phosphate ester or a substance taking part in the ATP conversion reaction in high sensitivity and high accuracy using an inexpensive and simple measuring apparatus.
