Anti-CCDC138 antibodies are used in the immunodetection of the protein coiled-coil domain containing 138. In humans, the canonical protein has a reported length of 665 amino acid residues and a mass of 76.2 kDa. Up to 2 different isoforms have been reported for this protein. It is notably expressed in the colon and testis. Synonyms for this target antigen include coiled-coil domain-containing protein 138. CCDC138 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Immunofluorescence is the most common application for the CCDC138 antibodies listed below. Western Blot and Immunohistochemistry are also common applications.
