Anti-SPINK14 antibodies are used in the immunodetection of the protein serine peptidase inhibitor Kazal type 14 (putative). In humans, the canonical protein has a reported length of 97 amino acid residues and a mass of 11.1 kDa. It has been described to be a secreted protein. SPINK14 is believed to be a serine protease inhibitor. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include serine protease inhibitor Kazal-type 14 and Kazal type serine protease inhibitor 5-like 2. SPINK14 gene orthologs have been reported in the mouse, rat and chimpanzee species.
