CST's PathScan® Phospho-IκB-α (Ser32) Sandwich ELISA Antibody Pair is offered as an economical alternative to our PathScan® Phospho-IκBα (Ser32) Sandwich ELISA Kit #7355. Capture and Detection antibodies (100X stocks) and HRP-conjugated secondary antibody (1000X stock) are supplied. Sufficient reagents are supplied for 4 x 96 well ELISAs. The IκBα Capture Antibody is coated in PBS overnight in a 96 well microplate. After blocking, cell lysates are added followed by a Phospho-IκBα (Ser32) Detection Antibody and anti-Rabbit IgG, HRP conjugated antibody. HRP substrate, TMB, is added for color development. The magnitude of the absorbance for this developed color is proportional to the quantity of Phospho-IκBα (Ser32) protein.
Antibodies in kit are custom formulations specific to kit.
Specificity / Sensitivity
For Antibody Pair specificity and sensitivity, please refer to the corresponding PathScan® Sandwich ELISA Kit. Note: This antibody pair detects proteins from the indicated species, as determined through in-house testing, but may also detect homologous proteins from other species.
The relationship between lysate protein concentration from untreated and TNF-α and IL-1β treated HeLa cells and the absorbance at 450 nm using PathScan® Phopho-IκBα (Ser32) Sandwich ELISA Antibody Pair #7343 is shown. HeLa cells were treated with TNF-α and IL-1β for 5 minutes at 37ºC and then lysed.
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).
