PROCESS AND REAGENT FOR DETERMINING MB-CREATINASE-ACTIVITY IN BODY-LIQUID-SAMPLES

摘要

A process for determination of CK-MB activity in a sample of a body fluid comprising the steps of incubating the sample, optionally in the presence of CK substrates, with antibodies which inhibit enzymatic activity of the M subunit in CK isoenzymes MM and MB without inactivating enzymatic activity of the B subunit in any CK-MB which may be present and determining the activity of the CK B subunit in the resultant sample.
