Abstract
A reagent for assaying creatine kinase, which contains glucokinase or hexokinase, glucose-6-phosphate dehydrogenase, adenosine 5'-diphosphate, creatine phosphate, oxidized nicotinamide adenine dinucleotide phosphate, magnesium salt, and glucose; and which comprises a first liquid reagent having a pH value of 7.5 to 10 and containing at least glucokinase and/or hexokinase, glucose-6-phosphate dehydrogenase, adenosine 5'-diphosphate and creatine phosphate, and a second liquid reagent having a pH value of 2 to 5 and containing at least oxidized nicotinamide adenine dinucleotide phosphate. The present reagent can be stably stored in the form of liquid for a long period of time at normal or low temperature in dark or light place. Therefore, it can be used without dissolution procedure after being preserved for a long term at the site of clinical examination and is also applicable to automatic analyzers.
