Description: Nuclear factor kappa B (NF-kappaB) is a ubiquitous transcription factor and an essential mediator of gene expression during activation of immune and inflammatory responses. The nuclear transcription factor kappa-B, NF-kappaB, is controlled by interaction with an inhibitory subunit, I-kappaB, which restricts NF-kappaB to the cytoplasm. Following stimulation by various cytokines or other stimuli, I-kappaB becomes degraded and NF-kappaB is released to the nucleus. The release of I-kappaB from NF-kappaB is thought to be a critical point in the activation of NF-kappaB signal pathways. A group of proteins form an NF-kappaB regulatory complex, or signalsome. Two members of this complex are a pair of closely related serine/threonine kinases, IKKalpha and IKKbeta (also called IKK-1 and IKK-2), which phosphorylate critical residues of I-kappaB, thus targeting it for subsequent degradation. The IKK complex contains similar amounts of IKKalpha, IKKbeta, as well as two other polypeptides, which are differentially processed forms of a third subunit, IKKgamma. IKKalpha and IKKbeta become activated following phosphorylation by upstream kinases, including NF-kappaB-inducing kinase (NIK) and MEKK1. IKKgamma interacts preferentially with IKKbeta and is required for the activation of the IKK complex. Experiments done on mice lacking IKKbeta demonstrate that these mice died at mid-gestation from uncontrolled liver apoptosis. Furthermore, when cells from IKKbeta-deficient m ice were treated with tumor necrosis factor alpha or interleukin 1, neither IKK nor NF-kappaB were activated. Thus IKKbeta, but not IKKalpha, plays a pivotal role in the induction of NF-kappaB and activation of IKK. IKKbeta migrates at ~87 kDa in SDS/PAGE. The antibody recognizes human IKKbeta. A recombinant protein corresponding to amino acids 1-666 of human IKKbeta was used as the immunogen.

Characteristics: 1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2. Please refer to us for technical protocols.
3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
4. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
