Western Blotting (WB), Immunohistochemistry (Paraffin-embedded Sections) (IHC (p))
Specificity
IkB-epsilon antibody detects endogenous levels of IkB-epsilon only when phosphorylated at serine 22.
Purification
The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific phosphopeptide. The antibody against non-phosphopeptide was removed by chromatography using non-phosphopeptide corresponding to the phosphorylation site.
Immunogen
The antiserum was produced against synthesized phosphopeptide derived from human IkB- epsilon around the phosphorylation site of serine 22 ( I-E-SP-L-R).

Background
NFKB1 or NFKB2 is bound to REL, RELA, or RELB to form the NFKB complex. The NFKB complex is inhibited by I-kappa-B proteins (NFKBIA, or NFKBIB), which inactivate NF-kappa-B by trapping it in the cytoplasm. Phosphorylation of serine residues on the I-kappa-B proteins by kinases (IKBKA, or IKBKB) marks them for destruction via the ubiquitination pathway, thereby allowing activation of the NF-kappa-B complex. Activated NFKB complex translocates into the nucleus and binds DNA at kappa-B-binding motifs such as 5-prime GGGRNNYYCC 3-prime or 5-prime HGGARNYYCC 3-prime (where H is A, C, or T, R is an A or G purine, and Y is a C or T pyrimidine). For some genes, activation requires NFKB interaction with other transcription factors, such as STAT, AP1 (JUN), and NFAT.Synonyms: I-kappa-B-epsilon, IkB-E, IkB-epsilon, IkappaBepsilon, NF-kappa-B inhibitor epsilon
