Anti-NFKB inhibitor beta antibodies are used for the immunodetection of the protein encoded by the NFKBIB gene. In humans, the canonical protein has a reported length of 356 amino acid residues and a mass of 37.8 kDa. Its subcellular localization is in the nucleus and cytoplasm. Alternative splicing is reported to yield 2 different isoforms for this protein. It is reported to be expressed in all tissues examined. A member of the NF-kappa-B inhibitor protein family, it is reported to inhibit NF-kappa-B by complexing with and trapping it in the cytoplasm. Other names for this target antigen include TRIP9, NF-kappa-B inhibitor beta, I-kappa-B-beta, NF-kappa-BIB, TR-interacting protein 9, TRIP-9, ikB-B, and IKBB. Gene orthologs have been identified in the mouse, rat, bovine, zebrafish, chimpanzee and chicken species. A number of NFKB inhibitor beta antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
