A method for determination of the creatine kinase isoenzyme mb ck mb is reported. Patterns of creatine kinase ck ec 2 7 3 2 isoenzymes were studied in apparently healthy one to 10 day old neonates by use of a sensitive fluorescent staining method with sclavo ck f 6001 reagent.
A cpk isoenzymes test can detect various muscle diseases or issues including.
Ck isoenzymes electrophoresis. As many proteins were separated by electrophoresis lactate dehydrogenase isoenzymes were detected stained specifically using a colorimetric method with an assay system in 0 1 m gly nacl naoh ph 8 3. Another at 48 hours may be needed. Total ck activity was used for calculation of ck mb level.
The hydragel 7 15 and 30 iso ck kits are designed for the identification and quantification of the three creatine kinase ck isoenzymes in human serum by electrophoresis on alkaline buffered ph 8 4 agarose gels. Separation of the isoenzymes was done by electrophoresis and the activity of the isoenzyme bands quantitated by scanning fluorometry. To support the diagnosis of ami three ck isoenzyme determinations have classically been recommended one on admission a second 12 hours after admission a third 24 hours after admission.
The precision of the method was. The kits are used in conjunction with the semi automated hydrasys electrophoresis system. Serum creatine kinase ck is separated into 3 isoenzymes by electrophoretic separation on agarose gel colorimetric results allow for improved workflow management as the gels do not have to be scanned immediately the permanent patterns combined with a clear gel background means scanning and quantitation are easy immunoassays are also commonly used.
Elevated levels of mb occur 4 to 6 hours after the onset of pain in myocardial infarction peak at 18 to 24 hours and persist upto 72 hours. A substrate that can be converted to a fluorescent product by ck can then be applied and the isoenzyme bands observed under uv light. 1 0 mol l sodium lactate 1 0 ml 10 mg ml nad 1 5 ml 1 0 mg ml nitro blue tetrazolium nbt 6 0 ml and 2 0 mg ml phenasine methosulfate psm 0 6 ml up to 30 ml with 0 1 m gly nacl naoh ph 8 3.
Ck mb usually peaks between 15 and 20 hours after the onset of a myocardial infarction. Dermatomyositis which is an. The resulting gels are ready for visual.
Ck cpk isoenzyme electrophoresis creatine phosphokinase activity is found in skeletal muscle myocardium and brain as isoenzymes mm mb and bb. Ck isoenzymes are separated electrophoretically on agarose plates at 90 v ph 8 6. Muscular dystrophy is a group of diseases that causes muscle loss and weakness over time.
