Anti-SERPINE3 antibodies are used in the immunodetection of the protein serpin family E member 3. In humans, the canonical protein has a reported length of 424 amino acid residues and a mass of 47 kDa. It has been described to be a secreted protein. Up to 2 different isoforms have been reported for this protein. A member of the Serpin protein family, SERPINE3 is a suspected serine protease inhibitor. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include serpin peptidase inhibitor, clade E (nexin, plasminogen activator inhibitor type 1), member 3, and nexin-related serine protease inhibitor. SERPINE3 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. ELISA, Western Blot, and Immunohistochemistry are common applications for SERPINE3 antibodies.
