Anti-SPINT3 antibodies are used in the immunodetection of the protein serine peptidase inhibitor, Kunitz type 3. In humans, the canonical protein has a reported length of 89 amino acid residues and a mass of 10.3 kDa. It has been described to be a secreted protein. It is notably expressed in the epididymis and skin. Synonyms for this target antigen include kunitz-type protease inhibitor 3, serine protease inhibitor, Kunitz type, 3, and HKIB9. SPINT3 gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. Indicated applications for SPINT3 antibodies listed below include Immunohistochemistry.
