Abstract
An enzymatic method for the analytical determination of creatine kinase in an aqueous liquid such as blood serum is described. The determination is made by measuring an optical density change using the reagents creatine phosphate, adenosine diphosphate, glycerol, glycerol kinase, .alpha.-glycerophosphate oxidase, a chromagen and a mercapto-containing creatine kinase activator. The mercapto-containing creatine kinase activator is added in encapsulated form or in low concentrations so as to preserve the activity of the chromagen.
