Used in biomedical research to measure rat cardiac troponin levels in serum or plasma samples. This assay helps assess myocardial injury in experimental models, such as drug-induced cardiotoxicity, ischemia-reperfusion studies, or evaluation of heart damage in preclinical trials. The kit enables sensitive and specific detection of troponin I or T, providing quantitative data useful in toxicology, pharmacology, and cardiovascular disease research. Results support evaluation of cardiac safety and efficacy of new therapeutic compounds in rodent models.
