Troponin C, Rabbit Skeletal Muscle Ag >95%

Purified calcium-binding subunit of the troponin complex, isolated from rabbit skeletal muscle, supplied by Antibodies.com as a ready-to-use liquid antigen. The protein retains its native two-domain architecture (N-terminal regulatory domain and C-terminal structural domain) that coordinates four calcium ions via EF-hand motifs, supporting its use as an immunogen, calibrator, or reference standard in muscle physiology research. Each preparation is purified to ≥95% homogeneity, enabling reproducible application as a coating antigen in ELISA, as a standard in Western blot workflows, and as a marker in immunohistochemistry of striated muscle sections.

The antigen is provided as a 1 mg aliquot in solution, allowing direct dilution into assay buffer without resolubilization. Investigators apply this reagent to studies of excitation-contraction coupling, myofilament calcium sensitivity, and the development of immunoassays that distinguish cardiac from skeletal troponin isoforms. For best results, store frozen in single-use aliquots and protect from repeated freeze-thaw cycles. For research use only.
