Product Introduction This product is used to detect the concentration of Creatine Kinase MB(CK-MB) in serum or plasma. Creatine kinase (CK) is an enzyme of two subunits M and/or B with three different pairs of subunits combine to give rise to three different isoenzymes CK-MB, CK-BB, and CK-MM. Those isoenzymes normally present in the cytosol, depending on the tissue: while CK-MB is expressed in cardiac muscle, CK-MM is expressed in sarcomeric muscle (both skeletal and cardiac muscle) and CK-BB is expressed in smooth muscle and most non-muscle tissues. Upon body injury, they are released into the blood and result in abnormally increased concentrations in serum or plasma. As a heart-specific isoenzyme, CK-MB can be used to assist diagnoses of acute myocardial infarction. The level of CK- MB in blood elevates in the fourth hour to the sixth hour after acute myocardial infarction and reaches the peak in the 18th-24th hours. Diseases rather than acute myocardial infarction may also cause elevated blood CK-MB. Other tests or diagnoses should be performed for comprehensive evaluations[1-3].
