Anti-SERPINB11 antibodies are used in the immunodetection of the protein serpin family B member 11. In humans, the canonical protein has a reported length of 392 amino acid residues and a mass of 44.1 kDa. Its subcellular localization is in the cytoplasm. Up to 3 different isoforms have been reported for this protein. It is notably expressed in a restricted number of tissues, including lung, placenta, prostate, and tonsil. A member of the Serpin protein family, SERPINB11 is known to have no serine protease inhibitory activity, probably due to mutations in the scaffold impairing conformational change. Synonyms for this target antigen include serpin peptidase inhibitor, clade B (ovalbumin), member 11, and serine (or cysteine) proteinase inhibitor, clade B (ovalbumin), member 11. SERPINB11 gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. Some SERPINB11 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
