IkB-ε (phospho-S22) polyclonal antibody

IkB-ε (I-kappa-B-epsilon), also known as NFKBIE (NFκB inhibitor epsilon) or IKBE, is a 500 amino acid protein that belongs to the NFκB inhibitor family. Localizing to the cytoplasm, IkB-ε is highly expressed in spleen, testis and lung, with lower levels of expression found in kidney, pancreas, heart, placenta, brain, granulocytes and macrophages. IkB-ε inhibits c-Rel and NFκB subunits p50, p52 and p65 by forming a complex with them in the cytoplasm, preventing them from activating genes in the nucleus. IkB-ε undergoes serine phosphorylation, resulting in the protein being marked for destruction via the ubiquitination pathway.

The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen and the purity is > 95% (by SDS-PAGE) .
