Anti-WDR31 antibodies are used in the immunodetection of the protein WD repeat domain 31. In humans, the canonical protein has a reported length of 367 amino acid residues and a mass of 40.8 kDa. Up to 2 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. Synonyms for this target antigen include WD repeat-containing protein 31. WDR31 gene orthologs have been reported in the mouse, rat, bovine, zebrafish, chimpanzee and chicken species. These WDR31 antibodies are widely used in Western Blot experiments, among other applications.
