Cardiac troponin I, encoded by the TNNI3 gene, serves as the inhibitory subunit of the troponin complex that regulates calcium-dependent muscle contraction in cardiac tissue. As a highly specific marker of myocardial injury, TNNI3 has become indispensable in cardiovascular research, from studying cardiomyopathies and heart failure mechanisms to investigating cardiac differentiation in stem cell models. Its restricted expression in heart muscle makes it a valuable tool for identifying cardiac lineage cells and assessing myocardial damage in experimental settings.
This recombinant monoclonal antibody, generated against a synthetic peptide derived from human TNNI3, offers the reproducibility that demanding research protocols require. Because recombinant antibodies are produced from defined genetic sequences rather than traditional hybridoma methods, you can expect consistent performance across different lots, eliminating the variability that can complicate longitudinal studies or multi-site collaborations. The rabbit IgG format, purified by affinity chromatography, delivers the specificity needed for reliable target detection.
Validation studies demonstrate effective performance in immunohistochemistry applications on paraffin-embedded human tissues. Testing on human heart tissue confirms detection in the expected physiological context, while examination of liver cancer tissue provides useful negative control data given the cardiac-restricted expression pattern of TNNI3. For IHC applications, dilutions between 1:50 and 1:200 provide a working range to optimize signal intensity for your specific tissue preparations and detection systems. The antibody is also validated for ELISA, offering flexibility for researchers requiring both tissue-based and quantitative approaches.
This antibody supports investigations into cardiac biology, myocardial pathology, and stem cell-derived cardiomyocyte characterization, providing a reliable tool for researchers exploring heart development and disease.
