Anti-Kininogen 1 antibodies are used for the immunodetection of the protein encoded by the KNG1 gene. In humans, the canonical protein has a reported length of 644 amino acid residues and a mass of 72 kDa. It is known to be a secreted protein. Alternative splicing is reported to yield 3 different isoforms for this protein. It is noted to be involved in inflammatory response pathways and the regulation of apoptosis. Post-translational modifications have been described, including O-glycosylation and phosphorylation. The gene encoding this protein is implicated in High molecular weight kininogen deficiency. Other names for this target antigen include BK, HAE6, HK, HMWK, KNG, alpha-2-thiol proteinase inhibitor, bradykinin, and BDK. Gene orthologs have been identified in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of Kininogen 1 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.
