Used in biomedical research to quantify levels of cardiac troponin I in blood samples, aiding in the study of myocardial injury and heart disease. Enables detection of early cardiac damage in experimental models, supporting drug development and evaluation of cardiotoxicity. Commonly applied in preclinical studies, clinical research labs, and cardiovascular biomarker validation. Provides a reliable, sensitive method for measuring troponin I concentrations, helping assess heart muscle damage with high specificity.
