Abstract
Creatine kinase is determined by the reaction of creatine phosphate with adenosine diphosphate with the formation of adenosine triphosphate, reaction of the latter with luciferin and oxygen in the presence of luciferase and diadenosine pentaphosphate with the formation of oxyluciferin and adenosine monophosphate, and measurement of the light thereupon emitted, the reaction being performed with a saturated concentration of adenosine diphosphate and substrate, in the presence of 1 to 10 millimoles per liter of AMP at pH values of 5.8 to 7.5, with at least 50 units of luciferase per test. It is desirable to operate in the presence of diadenosine pentaphosphate or sodium fluoride and a sequestering agent.
