Used in biomedical research to detect and quantify CK-MB levels in rabbit serum, plasma, or tissue samples. Helps in studying myocardial injury, especially in experimental models of heart damage. Enables researchers to assess cardiac muscle damage and evaluate the effectiveness of therapeutic interventions in preclinical studies. Provides a reliable and sensitive method for measuring CK-MB, a biomarker associated with heart tissue stress or infarction, in rabbit models.
