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.
Purification The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.
Background NF-kappaB is a ubiquitously expressed transcription factor that regulates many cytokine and Ig genes. It consists of homo- and heterodimeric proteins that belong to the Rel family of transcription factors. Rel proteins such as p50, p52, p65 (RelA), c-Rel, and RelB contain a Rel homology region (RHR) that includes DNA-binding and dimerization domains and a nuclear localization signal. Inactive NF-kappaB complexes are associated with their inhibitory IkappaB proteins. Several IkappaB proteins have been characterized including IkappaBalpha, IkappaBbeta, and IkappaBepsilon. They contain ankyrin repeats that interact with Rel RHR regions to form complexes in the cytoplasm that prevent nuclear translocation of NF-kappaB. In response to stimuli such as cytokines, LPS, and viral infections, IkappaB proteins are phosphorylated at critical residues by IkappaB kinases (IKKalpha and IKKbeta) leading to proteolysis of IkappaB proteins. This frees the heterodimeric NF-kappaB to form a heterotetramer that translocates to the nucleus and acts as a transcriptional activator. IkappaBepsilon may function primarily in the cytoplasm where it sequesters p65 and c-Rel, while IkappaBalpha and IkappaBbeta have additional functions that involve entering the nucleus to inhibit Rel DNA binding.
