    Product Information

    Product Description

    This Cell Signaling Technology® antibody is the biotinylated version of the unconjugated Phospho-IkappaB alpha (Ser32) (14D4) Rabbit Monoclonal Antibody #2859 and is expected to exhibit the same species cross-reactivity. The concentration of the biotinylated antibody is 500 ug/ml. Peptide ELISA data were generated using the biotinylated antibody. Western blot data were generated using the unconjugated antibody.
    MW (kDa) 40

    Product Usage Information

    Biotinylated antibodies are ideal for immunoassay technologies and high-throughput ELISA platforms that require antibody pairs where both antibodies are from the same host. Platforms utilizing biotinylated antibodies include, but are not limited to, MSD, xMAP, Quanterix Simoa, AlphaLISA, AlphaScreen, HTRF, LANCE, and TR-FRET.

    Optimal dilutions/working concentrations should be determined by the end user. Please contact us if you require the antibody clone biotinylated at a different concentration, a carrier-free formulation, or a more customized packaging solution.

    Storage

    Supplied in 140 mM NaCl, 3 mM KCl, 10 mM sodium phosphate (pH 7.4) dibasic, 2 mM potassium phosphate monobasic, 2 mg/mL BSA, and 50% glycerol. Store at –20°C. Do not aliquot the antibody.

    Protocol

    Specificity / Sensitivity

    Phospho-IkappaB alpha (Ser32) (14D4) Rabbit Monoclonal Antibody (Biotinylated) detects endogenous levels of IκBα only when phosphorylated at Ser32.

    Source / Purification

    Monoclonal antibody is produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Ser32 of human IκBα.

    Background

    The NF-κB/Rel transcription factors are present in the cytosol in an inactive state complexed with the inhibitory IκB proteins (1-3). Activation occurs via phosphorylation of IκBα at Ser32 and Ser36 followed by proteasome-mediated degradation that results in the release and nuclear translocation of active NF-κB (3-7). IκBα phosphorylation and resulting Rel-dependent transcription are activated by a highly diverse group of extracellular signals including inflammatory cytokines, growth factors, and chemokines. Kinases that phosphorylate IκB at these activating sites have been identified (8).
