Jurkat cells were treated for 30 min with 100 ug/ml ALLN (N-Acetyl-Leu-Leu-Norleucinal; a Calpain inhibitor and also proteasome inhibitor that prevents IkBa dephosphorylation) followed by incubation with (lanes 2 & 4) or without 1 nM TNF-a (1 & 3). The membranes were blotted with a IKB Alpha monoclonal antibody (Product # MA5-16152) (lanes 1 & 2) or a IKB Alpha monoclonal antibody (Product # MA5-16152) (that recognizes both non-phospho and phosphorylated forms of IkBa) and immunoreactivity was detected by ECL. The data shows that a IKB Alpha monoclonal antibody (Product # MA5-16152) detects specifically the phosphorylated form of IkBa.

NF-kB is silenced in the cytoplasm by an inhibitory protein, IkB (1). Synthesis of IkBa is autoregulated (2). IkB proteins are phosphorylated by IkB kinase complex consisting of at least three proteins, IKK1/a, IKK2/b, and IKK3/g (3-6). External stimuli such as tumor necrosis factor or other cytokines results in phosphorylation and degradation of IkB releasing NF-kB dimers. NF-kB dimer subsequently translocates to the nucleus and activates target genes. Six members of IkB family members have been identified (1). One of the first gene induced following NF-kB activation is IkBa.
