Creatine Kinase MB (CK-MB) Antigen

Targeting the cardiac isoform of creatine kinase, this 1 mg liquid antigen preparation from Antibodies.com is supplied for cardiovascular biomarker research, immunoassay development, and analytical method validation. CK-MB is one of the principal biomarkers evaluated in clinical studies of myocardial injury, rising within hours of cardiomyocyte damage and remaining diagnostically informative alongside troponin and total creatine kinase measurements.

Researchers apply this antigen as an immunogen for monoclonal and polyclonal antibody generation, as a calibrator or positive control in ELISA, chemiluminescence, and lateral flow assay development, and as a reference standard in electrophoretic and chromatographic characterization of the CK-MB isoenzyme. The protein supports reproducibility studies in antibody pairing, epitope mapping, and batch-to-batch comparison of capture and detection reagents.

The liquid formulation allows direct dilution into assay buffer, enabling reproducible standard curves and consistent performance in acute coronary syndrome research, point-of-care cardiac diagnostics development, and clinical chemistry method validation workflows.
