Used for the quantitative measurement of alpha-hydroxybutyrate dehydrogenase (αHBDH) activity in rat biological samples such as serum, plasma, or tissue homogenates. This ELISA kit enables researchers to assess myocardial or cellular damage in preclinical studies, particularly in models of heart disease or metabolic disorders. It is commonly applied in pharmaceutical research, toxicology studies, and biomarker validation where accurate detection of enzyme activity reflects tissue health or injury. The assay is sensitive, specific, and suitable for high-throughput analysis in laboratory settings.
