Application Note: IKKε pT501 antibody is tested in ELISA, western blotting, and although not tested, this antibody is likely functional in immunohistochemistry and immunoprecipitation. An 85 kDa band corresponding to human IKKe is detected. HeLa cells or TNF inducible KBM-5 cells can be used as a positive control. Researchers should determine optimal titers for other applications.

Immunogen: IKKe phospho peptide corresponding to a region of the human protein surrounding pT501 conjugated to KLH.
Physical State: Liquid (sterile filtered)
Purity and Specificity: Anti-IKKε pT501 antibody was affinity purified from monospecific antiserum by immunoaffinity purification against the phosphopeptide and cross adsorption against the non-phosphorylated form of the peptide followed by non-adsorption against a non-specific peptide backbone to further reduce non-specific reactivity. This phospho specific polyclonal antibody is specific for phosphorylated pT501 human IKKe. Reactivity with non-phosphorylated IKKe is minimal. Cross reactivity with pT501 phosphorylated IKKe from mouse, rat or other species has not been determined.
Background: Nuclear Factor kappa B (NF-kB) is a ubiquitous transcription factor and an essential mediator of gene expression during the activation of immune and inflammatory responses. NF-kB mediates the expression of a great variety of genes in response to extracellular stimuli. NF-kB is associated with IkB proteins in the cytoplasm of the cell, which inhibit NF-kB activity. IkB proteins are phosphorylated by an IkB kinase complex consisting of at least three proteins, IKKa, IKKb, and IKKg. Isolated from a cDNA library of LPS-stimulated mouse macrophage cells, a novel molecule in the IKK complex has been recently identified and designated IKKi and/or IKKe. IKKepsilon is required for the activation of NF-kB by mitogens and T cell receptors but not by TNFα or IL-1. LPS increases the IKKe mRNA level in mouse macrophage cell lines. This protein has significant sequence homology with kinase domains of IKKa and IKKb. Overexpression of wild type IKKe in cells phosphorylates Ser32 and Ser36 of IkBa. Anti-IKKε pT501 antibody is ideal for investigators involved in NFkappaB and apoptosis research.
