CST's PathScan® Phospho-IκBα (Ser32) Sandwich ELISA Kit is a solid phase sandwich enzyme-linked immunosorbent assay (ELISA) that detects endogenous levels of Phospho-IκBα (Ser32) protein. An IκBα Mouse mAb has been coated onto the microwells. After incubation with cell lysates, both nonphospho- and phospho-IκBα proteins are captured by the coated antibody. Following extensive washing, Phospho-IκBα (Ser32) Antibody is added to detect the captured phospho-IκBα (Ser32) protein. Anti-rabbit IgG, HRP-linked antibody is then used to recognize the bound detection antibody. HRP substrate, TMB, is added to develop color. The magnitude of optical density for this developed color is proportional to the quantity of phospho-IκBα (Ser32) protein.Antibodies in kit are custom formulations specific to kit.

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).

The FastScan™ Phospho-IκBα (Ser32) ELISA Kit is a sandwich enzyme-linked immunosorbent assay (ELISA) that detects endogenous levels of IκBα when phosphorylated at Ser32. To perform the assay, sample is incubated with a capture antibody conjugated with a proprietary tag and a second detection antibody linked to HRP, forming a sandwich with phospho-IκBα (Ser32) in solution. This entire complex is immobilized to the plate via an anti-tag antibody. The wells are then washed to remove unbound material. TMB is then added. The magnitude of observed signal is proportional to the quantity of phospho-IκBα (Ser32). Antibodies in kit are custom formulations specific to kit.

CST's PathScan® Total IκBα Sandwich ELISA Kit is a solid phase sandwich enzyme-linked immunosorbent assay (ELISA) that detects endogenous levels of total IκBα protein. An IκBα Mouse mAb has been coated onto the microwells. After incubation with cell lysates, both nonphospho- and phospho-IκBα proteins are captured by the coated antibody. Following extensive washing, an IκBα Rabbit Antibody is added to detect the captured IκBα protein. Anti-rabbit IgG, HRP-linked antibody is then used to recognize the bound detection antibody.
