Anti-epithelial mitogen antibodies are used for the immunodetection of the protein encoded by the EPGN gene. In humans, the canonical protein has a reported length of 154 amino acid residues and a mass of 17.1 kDa. It is known to be a secreted protein. Alternative splicing is reported to yield 7 different isoforms for this protein. It is reported to promote the growth of epithelial cells. Post-translational modifications have been described, including glycosylation. Other names for this target antigen include epigen and epithelial mitogen homolog. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of epithelial mitogen antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
