Anti-SERPINB2 antibodies are used in the immunodetection of the protein serpin family B member 2. In humans, the canonical protein has a reported length of 415 amino acid residues and a mass of 46.6 kDa. Its subcellular localization is in the cytoplasm. It is notably expressed in the skin, placenta, and esophagus. A member of the Serpin protein family, SERPINB2 is reported to inhibit urokinase-type plasminogen activator. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include PAI, PAI2, PLANH2, plasminogen activator inhibitor 2, and HsT1201. SERPINB2 gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. A number of SERPINB2 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Flow Cytometry and Immunohistochemistry are also common applications.
