The detection of creatine kinase isoenzyme CK1 in serum.
The brain isoenzyme of creatine kinase (CK) (EC 2.7.3.2) has been identified in the serum of 21 of 950 patients tested. Samples were received over a period of about 20 months. Analysis was performed by electrophoresis on agarose gel with isoenzyme bands visualized by fluorescence after enzyme coupled reactions producing NADH. Specialized substrate preparations were used to rule out the possibil...
متن کاملMyocardial creatine kinase isoenzyme in serum after subarachnoid haemorrhage.
The myocardial isoenzyme of creatine kinase (MB CK) has been demonstrated in the serum of seven of 16 patients presenting with acute subarachnoid haemorrhage. All patients with elevated MB CK levels exhibited at some stage either intracranial arterial spasm as demonstrated by cerebral angiography, or a focal reversible neurological deficit not due to direct pressure by either intracranial haema...
متن کاملRadioimmunoassay of creatine kinase isoenzymes in human serum: isoenzyme BB.
We describe a sensitive, specific radioimmunoassay for the BB isoenzyme of creatine kinase (CK-BB) in serum. A sequential saturation assay was used to achieve sufficient sensitivity to detect the isoenzyme in 100-microliter serum samples of all healthy persons and patients tested. Bound and free antigen were separated by a second antibody system. Large excesses of purified isoenzyme MM did not ...
متن کاملMeasurement of brain-specific creatine kinase isoenzyme activity in serum.
We have modified the columti-chromatographic technique of Mercer (1) to produce a sensitive and rapid separation of serum CK2 and CK3, even at normal total serum CK activity (3).12 However, CKj was not separated from CK2. Here, we report a modification of our method such that all three CK isoenzymes are separated by stepwise elution from a mini-column of diethylaminoethyl-cellulose. CK1 has onl...
متن کاملQuantification of cerebral infarct size by creatine kinase BB isoenzyme.
Creatine Kinase BB isoenzyme (CKBB) has been shown to rise in the serum and CSF following acute cerebral injury. To test the hypothesis that brain infarct size could be estimated from the appearance and disappearance of CKBB in the serum and CSF, strokes of varying size were produced in twelve mongrel dogs by silastic emboli. The rate of disappearance, Kd of CKBB (-.00732 +/- 0.001 min-1 mean +...
