ELISA 1/5000 - 1/25000.
Dot blot Use at an assay dependent concentration.


  • Function
    Inhibits NF-kappa-B by complexing with and trapping it in the cytoplasm. However, the unphosphorylated form resynthesized after cell stimulation is able to bind NF-kappa-B allowing its transport to the nucleus and protecting it to further NFKBIA-dependent inactivation. Association with inhibitor kappa B-interacting NKIRAS1 and NKIRAS2 prevent its phosphorylation rendering it more resistant to degradation, explaining its slower degradation.
  • Tissue specificity
    Expressed in all tissues examined.
  • Sequence similarities
    Belongs to the NF-kappa-B inhibitor family.
    Contains 6 ANK repeats.
  • Post-translational
    Phosphorylated by RPS6KA1; followed by degradation. Interaction with NKIRAS1 and NKIRAS2 probably prevents phosphorylation.
  • Cellular localization
    Cytoplasm. Nucleus.

  • Detection of IkB beta by Immunoprecipitation in whole cell lysate from Huh-7 cells, using ab7547 at 4 µg/mg lysate for IP and ab1162 at a 1/1500 dilution for subsequent Western blot detection.
    Cells expressed recombinant IkB beta tagged with DDDDK. Protein A was used for the Immunoprecipitation step. Primary antibody incubated with matrix for 4 hours at 4°C.

  • ICC/IF image of ab7547 stained HeLa cells. The cells were 100% methanol fixed (5 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab7547, 1/100 dilution) overnight at +4°C. The secondary antibody (green) was ab96899 Dylight 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
