Anti-SERPINB12 antibodies are used in the immunodetection of the protein serpin family B member 12. In humans, the canonical protein has a reported length of 405 amino acid residues and a mass of 46.3 kDa. Its subcellular localization is in the cytoplasm. Up to 2 different isoforms have been reported for this protein. It is reported to be expressed in many tissues, including brain, bone marrow, lymph node, heart, lung, liver, pancreas, testis, ovary, and intestine. A member of the Serpin protein family, SERPINB12 is reported to inhibit trypsin and plasmin, but not thrombin, coagulation factor Xa, or urokinase-type plasminogen activator. Synonyms for this target antigen include serpin peptidase inhibitor, clade B (ovalbumin), member 12, and serine (or cysteine) proteinase inhibitor, clade B (ovalbumin), member 12. SERPINB12 gene orthologs have been reported in the mouse, rat and chimpanzee species. Some SERPINB12 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunofluorescence are also common applications.
