From 2000 sera with elevated total creatine kinase (EC 2.7.3.2) activity the sera of 6 patients showed a persistent high and anamnestically inexplicable creatine kinase activity level. The serum isoenzyme pattern was analyzed by four different methods. Electrophoresis revealed an atypical creatine kinase activity band located between creatine kinase-MM and creatine kinase-MB. An adequate estimation of the persistent enzyme activity could only be achieved by immunotitration (immunoprecipitation), which identified the creatine kinase activity as due primarily to the isoenzyme creatine kinase-BB. Other methods (immunoinhibition and column chromato-graphy) may lead to misinterpretations. The atypical serum creatine kinase-BB showed a higher mol...
