Anti-PROZ antibodies are used in the immunodetection of the protein protein Z, vitamin K dependent plasma glycoprotein. In humans, the canonical protein has a reported length of 400 amino acid residues and a mass of 44.7 kDa. It has been described to be a secreted protein. Up to 2 different isoforms have been reported for this protein. It is notably expressed in plasma. A member of the Peptidase S1 protein family, PROZ is known to be involved with proteolysis. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include PZ and vitamin K-dependent protein Z. PROZ gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Some PROZ antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
