Used in biomedical research to measure phosphocreatine kinase (CPK) levels in rat samples, this ELISA kit enables accurate quantification of CPK enzyme concentration in serum, plasma, or tissue homogenates. It is commonly applied in studies related to muscle damage, myocardial infarction, and neurological disorders in rat models. The assay helps researchers assess cellular stress, muscle integrity, and the efficacy of therapeutic interventions in preclinical experiments. Due to its high sensitivity and specificity, the kit supports reliable data collection in neuroscience, cardiology, and toxicology research.
