Product Data

• Applications: IHC
• Recommended Dilution: Immunohistochemistry: 1:50~1:100.
• Reactivities: Human
• Host: Rabbit
• Clonality: Polyclonal
• Immunogen: The antiserum was produced against synthesized phosphopeptide derived from human IκB-β around the phosphorylation site of serine 23 (L-G-SP-L-G ).
• Specificity: IκB-β antibody detects endogenous levels of total IκB-β protein.
• Formulation: PBS(without Mg2+ and Ca2+), pH 7.4 containing 150mM NaCl, 0.02% sodium azide and 50% glycerol
  State: Aff - Purified
  State: Liquid purified IgG
• Concentration: lot specific
• 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.
• Conjugation: Unconjugated
• Storage: Store the antibody at -20°C.
  Avoid repeated freezing and thawing.
• Stability: Shelf life: one year from despatch.
• Gene Name: NFKB inhibitor beta
• Database Link:
  Entrez Gene 4793 Human
  UniProt ID Q15653
• Background: Three major forms of IkB-like molecules have been identified and each is characterized by multiple copies of ankyrin repeats. IkB-alpha and IkB-beta appear to be the major regulatory forms of IkB in most cells. These proteins interact with p65 or c-Rel containing forms of NFkB and block nuclear import by masking the nuclear localization sequences of NFkB. The activation of NFkB involves the inducible phosphorylation and subsequent degradation of IkB. Immunoblotting easily detects the hyper-phosphorylated forms of IkB-alpha, but not phosphorylated IkB-beta. Interestingly, IkB-alpha and IkB-beta mediate different NFkB responses. IkB-alpha appears to control more transient activation of NFkB in response to an inducer, while IkB-beta controls a persistent response. Bcl-3 interacts with p50 and p52 containing forms of NFkB, but rather than being an inhibitor it appears to function to stimulate transcription. The degradation of IkB is confirmed by immunoblotting.
