Human Cardiac Troponin I (Active)

The Antibodies.com Human Cardiac Troponin I (Active) preparation is a purified native protein isolated from human cardiac tissue, supplied as a 100 µg liquid formulation in a vial. This biologically active form retains its calcium-binding and actomyosin ATPase regulatory function, making it valuable as a calibrator or reference standard in cardiac biomarker research. The protein migrates at approximately 24 kDa on SDS-PAGE and exhibits cardiac-specific isoform expression, with negligible cross-reactivity toward skeletal troponin I isoforms, a property that underpins its diagnostic specificity for myocardial injury studies. Recommended for use in immunoassay development, acute myocardial infarction biomarker investigations, and cardiac muscle physiology research. For handling, store frozen at -20 °C or below in working aliquots to preserve activity, and avoid repeated freeze-thaw cycles.
