Used for the quantitative measurement of creatine kinase (CK) enzyme activity in mouse biological samples such as serum, plasma, tissue homogenates, and cell culture supernatants. This ELISA kit is specifically designed to detect CK activity levels in preclinical research involving muscle damage, myocardial infarction, neurodegenerative diseases, and inflammatory conditions in mouse models. It enables researchers to assess muscle integrity and monitor disease progression or treatment efficacy in experimental studies related to muscular dystrophy, exercise-induced injury, and cardiac dysfunction. The assay provides high sensitivity and specificity, allowing accurate detection of CK changes even at low concentrations. It is widely used in biomedical research laboratories and pharmaceutical development for evaluating biomarkers in mouse-based disease models.
