Anti-MEGF9 antibodies are used in the immunodetection of the protein multiple EGF like domains 9. In humans, the canonical protein has a reported length of 602 amino acid residues and a mass of 63 kDa. Its subcellular localization is in the membrane. It is notably widely expressed in many tissue types. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include multiple epidermal growth factor-like domains protein 9, EGF-like-domain, multiple 5, epidermal growth factor-like protein 5, and EGFL5. MEGF9 gene orthologs have been reported in the mouse, rat, bovine, chimpanzee and chicken species. Some MEGF9 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
