Anti-R3HDM4 antibodies are used in the immunodetection of the protein R3H domain containing 4. In humans, the canonical protein has a reported length of 268 amino acid residues and a mass of 30.4 kDa. Its subcellular localization is in the nucleus. Synonyms for this target antigen include R3H domain-containing protein 4 and R3H domain-containing protein C19orf22. R3HDM4 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. These R3HDM4 antibodies are widely used in Western Blot experiments, among other applications.
