Clinical application of subforms of creatine kinase MM and macro creatine kinases.
The subforms of MM isozyme of creatine kinase (ATP:creatine N-phosphotransferase, EC 2.7.3.2, CK) in sera obtained from healthy adults and patients were determined by agarose gel isoelectric focusing (IEF). The patients were classified into six groups according to serum CK-MM activities and IEF patterns. The IEF spectra offered useful information on cell hyperplasia, augmented cell membrane permeability, cell destruction and release time of CK-MM in the circulation from the cells for diagnosis, progress observation and prognosis, especially in the cases of chronic hepatic diseases, acute myocardial infarction and muscular dystrophy. Macro CKs were also determined by IEF. Macro CKs could be completely distinguished from each other, and CK isozymes consisting of macro CK type 1 could be presumed by isoelectric points.
