Product Information
Product Description
The PathScan® Phospho-IKKα (Ser176/180) Sandwich ELISA Kit is a solid phase sandwich enzyme-linked immunosorbent assay (ELISA) that detects endogenous levels of IKKα when phosphorylated at Ser176/180. A phospho-IKKα (Ser176/180) rabbit mAb has been coated onto the microwells. After incubation with cell lysates, phospho-IKKα (Ser176/180) protein is captured by the coated antibody. Following extensive washing, an IKKα mouse detection mAb is added to detect the captured IKKα protein. Anti-mouse IgG, HRP-linked antibody is then used to recognize the bound detection antibody. HRP substrate, TMB, is added to develop color. The magnitude of the absorbance for the developed color is proportional to the quantity of IKKα phosphorylated at Ser176/180.

Protocol
Specificity / Sensitivity
The PathScan® Phospho-IKKα (Ser176/180) Sandwich ELISA Kit detects endogenous levels of IKKα protein when phosphorylated at Ser176/180, as shown in Figure 1. The kit sensitivity is shown in Figure 2. This kit detects proteins from the indicated species, as determined through in-house testing, but may also detect homologous proteins from other species.

Background
The NF-κB/Rel transcription factors are present in the cytosol in an inactive state, complexed with the inhibitory IκB proteins (1-3). Most agents that activate NF-κB do so through a common pathway based on phosphorylation-induced, proteasome-mediated degradation of IκB (3-7). The key regulatory step in this pathway involves activation of a high molecular weight IκB kinase (IKK) complex whose catalysis is generally carried out by three tightly associated IKK subunits. IKKα and IKKβ serve as the catalytic subunits of the kinase and IKKγ serves as the regulatory subunit (8,9). Activation of IKK depends upon phosphorylation at Ser177 and Ser181 in the activation loop of IKKβ (Ser176 and Ser180 in IKKα), which causes conformational changes, resulting in kinase activation (10-13).
