Anti-POLD2 antibodies are used in the immunodetection of the protein DNA polymerase delta 2, accessory subunit. In humans, the canonical protein has a reported length of 469 amino acid residues and a mass of 51.3 kDa. Its subcellular localization is in the nucleus. It is notably widely expressed in many tissue types. A member of the DNA polymerase delta/II small subunit protein family, POLD2 is reported to be an accessory component of both the DNA polymerase delta complex and the DNA polymerase zeta complex. Synonyms for this target antigen include DAN polymerase delta 2, accessory subunit, DNA polymerase delta subunit p50, Pol delta B subunit (p50), polymerase (DNA directed), delta 2, accessory subunit, and DNA polymerase delta subunit 2. POLD2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of POLD2 antibodies have been mentioned in research publications and have associated citations. These antibodies are most commonly used in Western Blot experiments, among other applications.
