Anti-VDAC2 antibodies are used in the immunodetection of the protein voltage dependent anion channel 2. In humans, the canonical protein has a reported length of 294 amino acid residues and a mass of 31.6 kDa. Its subcellular localization is in the mitochondria. Up to 3 different isoforms have been reported for this protein. It is reported to be expressed in erythrocytes. A member of the Eukaryotic mitochondrial porin protein family, VDAC2 is known to be involved with the transport of ions and the regulation of apoptosis. Synonyms for this target antigen include voltage-dependent anion-selective channel protein 2, epididymis secretory sperm binding protein, outer mitochondrial membrane protein porin 2, and POR. VDAC2 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Over 80 citations in the literature describe the use of VDAC2 antibodies in research. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
