Used in biomedical research to detect and quantify pig cardiac troponin I levels in serum or plasma samples. Enables assessment of myocardial injury in experimental models, particularly in studies related to heart disease, drug toxicity, or cardiovascular interventions in swine. Commonly applied in preclinical research due to the physiological similarity between pig and human hearts. Supports evaluation of cardiac biomarkers during drug development, ischemia-reperfusion studies, and cardiotoxicity screening. Provides a reliable, sensitive, and specific measurement method essential for accurate data collection in cardiac function and damage studies.
