Anti-SCN3B antibodies are used in the immunodetection of the protein sodium voltage-gated channel beta subunit 3. In humans, the canonical protein has a reported length of 215 amino acid residues and a mass of 24.7 kDa. Its subcellular localization is in the membrane. It is reported to be expressed in the atrium. A member of the Sodium channel auxiliary subunit SCN3B (TC 8.A.17) protein family, SCN3B is known to be involved with nervous system development and the transport of ions. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include sodium channel, voltage-gated, type III, beta subunit, voltage-gated sodium channel beta-3 subunit, and sodium channel subunit beta-3. SCN3B gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some SCN3B antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. Immunocytochemistry and Immunofluorescence are also common applications.
