Used in cardiovascular research to detect and quantify highly sensitive cardiac troponin T levels in rat models. Enables early detection of myocardial injury, assessment of drug-induced cardiotoxicity, and evaluation of heart damage in experimental studies. Widely applied in preclinical drug development and toxicology studies to monitor cardiac safety. Supports research in ischemia-reperfusion injury, myocardial infarction, and heart failure models in rats. Provides high sensitivity and specificity for reliable measurement of low-concentration troponin T in small sample volumes.
