Anti-SPINT2 antibodies are used in the immunodetection of the protein serine peptidase inhibitor, Kunitz type 2. In humans, the canonical protein has a reported length of 252 amino acid residues and a mass of 28.2 kDa. Its subcellular localization is in the membrane. Up to 2 different isoforms have been reported for this protein. It is reported to be expressed in the placenta, kidney, pancreas, prostate, testis, thymus, and trachea. SPINT2 is known as an inhibitor of HGF activator. Post-translational modifications have been described, including glycosylation. The SPINT2 gene has been associated with the disease, Diarrhea. Synonyms for this target antigen include HAI-2, HAI2, Kop, PB, kunitz-type protease inhibitor 2, and DIAR3. SPINT2 gene orthologs have been reported in the mouse, rat, bovine, chimpanzee and chicken species. A number of SPINT2 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
