Used to measure the activity of human alpha-hydroxybutyrate dehydrogenase (αHBDH) in biological samples such as serum, plasma, or cell lysates. This assay helps in assessing heart and liver function, as elevated αHBDH levels are associated with myocardial infarction, liver disease, and other metabolic disorders. The ELISA kit format allows for high sensitivity and specificity, making it suitable for clinical diagnostics and research settings where accurate quantification of enzyme activity is required. It is commonly used in hospitals, diagnostic laboratories, and biomedical research to support disease detection and monitoring.
