Used in biomedical research to detect and quantify levels of cardiac troponin I in rat samples, aiding in the assessment of myocardial injury or cardiac toxicity in preclinical studies. Commonly applied in pharmacology and toxicology to evaluate drug safety, monitor heart damage in experimental models, and support the development of cardiovascular therapies. The ELISA format allows for high sensitivity and specificity, making it suitable for measuring low concentrations of troponin I in serum or plasma.
