[The determination of creatine kinase isoenzyme subunits CK-M and CK-B with the help of precipitating antibodies].

Isoenzymes of creatine kinase (CK-MM and CK-BB) of samples of tissues from human skeletal muscle and human brain tissues were highly purified. Anti-CK-M and anti-CK-B were prepared by immunization of goats. The obtained antibodies were used in a modified immunoprecipitation method for measuring the creatine kinase subunits of CK-M and CK-B in serum.
