mouse monoclonal IgG2a; Troponin T-C Antibody (CT3) is an IgG2a κ mouse monoclonal Troponin T-C antibody (also designated TNNT2 antibody, cTnT antibody or Cardiac muscle Troponin T antibody) that detects the Troponin T-C protein of broad species origin by WB, IP, IF and IHC(P). Troponin T-C Antibody (CT3) is available as both the non-conjugated anti-Troponin T-C antibody form, as well as multiple conjugated forms of anti-Troponin T-C antibody, including agarose, HRP, PE, FITC and multiple Alexa Fluor® conjugates. Actin is a highly conserved protein that is expressed in all eukaryotic cells. Actin filaments can form both stable and labile structures and are crucial components of microvilli and the contractile apparatus of muscle cells. Myosin is a hexamer of two heavy chains (MHC) and four light chains (MLC) that interacts with Actin to generate the force for diverse cellular movements, including cytokinesis, phagocytosis and muscle contraction. Troponin facilitates the interaction between Actin and Myosin by binding to calcium. Troponin is made up of at least two subunits, which are divergent in cardiac muscle, fast skeletal muscle and slow skeletal muscle. Structures of skeletal muscle troponin are composed of Troponin C (the sensor), Troponin I (the regulator) and Troponin T (the link to the muscle thin filament). Troponin C is dumbbell-shaped and has a hydrophobic pocket that increases the contractile force of muscle fibers. Troponin C has two isoforms: fast and slow. Fast Troponin C has two calcium binding sites, while slow/cardiac Troponin C has a single calcium binding site.
