Anti-Sorcin antibodies are used for the immunodetection of the protein encoded by the SRI gene. In humans, the canonical protein has a reported length of 198 amino acid residues and a mass of 21.7 kDa. Its subcellular localization is in the membrane and cytoplasm. Alternative splicing is reported to yield 3 different isoforms for this protein. It is notably expressed in cardiac myocytes. It is reported to be a calcium-binding protein that modulates excitation-contraction coupling in the heart. Other names for this target antigen include CP22, SCN, V19, 22 kDa protein, H_RG167B05.1, and CP-22. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of Sorcin antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
