Anti-NFKB1 antibodies are used in the immunodetection of the protein nuclear factor kappa B subunit 1. In humans, the canonical protein has a reported length of 968 amino acid residues and a mass of 105.4 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 3 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. NFKB1 is known to be involved with the apoptotic pathway and the cellular response to lipopolysaccharides. Post-translational modifications have been described, including ubiquitination, palmitoylation, protein cleavage and phosphorylation. Synonyms for this target antigen include EBP-1, KBF1, NF-kB, NF-kappa-B1, NF-kappaB, NF-kappabeta, NFKB-p105, and CVID12. NFKB1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 840 citations in the literature describe the use of NFKB1 antibodies in research. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
