Anti-NFKBID antibodies are used in the immunodetection of the protein NFKB inhibitor delta. In humans, the canonical protein has a reported length of 313 amino acid residues and a mass of 33.5 kDa. Its subcellular localization is in the nucleus. Up to 3 different isoforms have been reported for this protein. A member of the NF-kappa-B inhibitor protein family, NFKBID is reported to regulate the expression of IL-2, IL-6, and other cytokines through regulation on NF-kappa-B activity. Synonyms for this target antigen include I-kappa-B-delta, T-cell activation NFKB-like protein, ikB-delta, ikappaBdelta, nuclear factor of kappa light polypeptide gene enhancer in B-cells inhibitor, delta, and NF-kappa-B inhibitor delta. NFKBID gene orthologs have been reported in the mouse, rat, bovine, frog and chimpanzee species. Some NFKBID antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
