Anti-Connexin-32 [M12.13] Antibody

This mouse IgG monoclonal antibody was raised against isolated rat hepatocyte gap junctions and recognizes human, mouse, and rat Gap junction beta-1 protein (Connexin-32).


  • Recognizes human, mouse and rat Connexin-32 on the cytoplasmic surface (residues 95-125)
  • Suitable for Western Blot and Immunohistochemistry

Connexins are membrane-spanning proteins that assemble to form gap junction channels that facilitate the transfer of ions and small molecules between cells. One gap junction consists of a cluster of closely packed pairs of transmembrane channels, the connexons, through which materials of low MW diffuse from one cell to a neighboring cell.
