The Creatine Kinase Isoenzyme (CK-MB) antigen antibody is an antibody used to detect CK-MB and can be used in immunology and biomedical research. CK-MB is a creatine kinase isoenzyme found primarily in the heart muscle. The level of CK-MB can be used to diagnose and evaluate heart diseases such as myocardial infarction. By detecting the binding of CK-MB antibodies to CK-MB, the level of CK-MB can be measured, helping to diagnose and evaluate heart disease. CK-MB antigen antibodies can also be used to study the function and regulatory mechanism of CK-MB, providing a powerful tool for biomedical research.
