The IKK-alpha (Phospho-Thr23) Colorimetric Cell-Based ELISA Kit is a convenient, lysate-free, high throughput and sensitive assay kit that can detect IKK-alpha protein phosphorylation and expression profile in cells. The kit can be used for measuring the relative amounts of phosphorylated IKK-alpha in cultured cells as well as screening for the effects that various treatments, inhibitors (ie. siRNA or chemicals), or activators have on IKK-alpha phosphorylation.

Qualitative determination of IKK-alpha (Phospho-Thr23) concentration is achieved by an indirect ELISA format. In essence, IKK-alpha (Phospho-Thr23) is captured by IKK-alpha (Phospho-Thr23)-specific primary (1ø) antibodies while the HRP-conjugated secondary (2ø) antibodies bind the Fc region of the 1ø antibody. Through this binding, the HRP enzyme conjugated to the 2ø antibody can catalyze a colorimetric reaction upon substrate addition. Due to the qualitative nature of the Cell-Based ELISA, multiple normalization methods are needed:

1. A monoclonal antibody specific for human GAPDH is included to serve as an internal positive control in normalizing the target absorbance values.
2. Following the colorimetric measurement of HRP activity via substrate addition, the Crystal Violet whole-cell staining method may be used to determine cell density. After staining, the results can be analysed by normalizing the absorbance values to cell amounts, by which the plating difference can be adjusted.
Database Information:Gene ID: 1147, UniProt ID: O15111, OMIM: 600664, Unigene: Hs.198998
Gene Symbol:CHUK
Sub Type:Phospho
UniProt Protein Function:IKKA: a kinase of the IKK family. Phosphorylates inhibitors of NF-kappa-B, leading to their dissociation from NF-kappa-B and ultimately to their degradation. Phosphorylated and activated downstream of growth factor receptors, IL1R, and TNFR by NAK, IRAK and NIK, respectively. Preferentially found as a heterodimer with IKK-beta but also as an homodimer. Directly interacts with IKK-gamma/NEMO and TRPC4AP. Heterodimers form the active complex. The tripartite complex can also bind to MAP3K14/NIK, MEKK1, IKAP and IKB-alpha-p65-p50 complex. Inhibitors are under development to treat arthritis, inflammation, and apoptotic aspects of cancer. Aspirin (sodium salicylate) selectively binds IKK and reduces inflammation. Misexpression and inhibitors show involvement in insulin sensitization in obese rodents. Mutations in IKK-gamma are found in several immune deficiencies: hyper IgM syndrome, incontinentia pigmenti [embryonic lethal in males, defects in skin, hair, teeth in females] and hypohidrotic ectodermal dysplasia; recurrent infections and defects in teeth, hair, and sweat glands]. Inhibitors: CHS 828, NBD peptide, BMS-345541.

NCBI Summary:This gene encodes a member of the serine/threonine protein kinase family. The encoded protein, a component of a cytokine-activated protein complex that is an inhibitor of the essential transcription factor NF-kappa-B complex, phosphorylates sites that trigger the degradation of the inhibitor via the ubiquination pathway, thereby activating the transcription factor.
