Troponin I, Human Skeletal Muscle Ag ≥98%

Supplied as a ready-to-use liquid preparation, this native antigen from Antibodies.com delivers purified human skeletal muscle troponin I at ≥98% purity, isolated directly from human skeletal muscle tissue. The protein retains its native conformation, supporting consistent performance as an assay calibrator, immunogen, or reference standard in muscle physiology research. Each vial contains 100 µg of protein; aliquot on receipt and store at -20 °C, avoiding repeated freeze-thaw cycles to preserve epitope integrity. Researchers can apply this antigen in Western blot characterization, immunohistochemistry controls, immunoassay development, and antibody validation work targeting isoform-specific epitopes, particularly where differentiation between cardiac and skeletal muscle troponin I isoforms is required. The native purification approach distinguishes this reagent from recombinant alternatives, providing authentic post-translational context for skeletal muscle isoform studies and cardiac biomarker cross-reactivity investigations.
