Anti-C22orf39 antibodies are used in the immunodetection of the protein chromosome 22 open reading frame 39. In humans, the canonical protein has a reported length of 142 amino acid residues and a mass of 16.8 kDa. Up to 2 different isoforms have been reported for this protein. It is a member of the UPF0545 protein family. Synonyms for this target antigen include UPF0545 protein C22orf39. C22orf39 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some C22orf39 antibodies may have been used in research and have associated citations. Immunofluorescence is a widely used application for these antibodies. In addition, Western Blot is also a common application.
