Ready-to-use ELISA kits are available for the detection of IkB zeta, an alias of the protein, NFKB inhibitor zeta. The official gene symbol is NFKBIZ. The protein, with a mass of 78.1 kDa and length of 718 residues, is reported to be nuclear. It may be known by other names, including: ikappaBzeta, ikB-zeta, Ikappa B-zeta variant 3, IL-1 inducible nuclear ankyrin-repeat protein, I-kappa-B-zeta, and NF-kappa-B inhibitor zeta, and nuclear factor of kappa light polypeptide gene enhancer in B-cells inhibitor zeta.
