Species cross-reactivity is determined by western blot using the unconjugated antibody.
Applications Key: W=Western Blotting
Specificity / Sensitivity
IκBα (L35A5) Mouse mAb (Amino-terminal Antigen) (Biotinylated) detects endogenous levels of total IκBα protein.
Source / Purification
Monoclonal antibody is produced by immunizing animals with a GST-IκBα fusion protein corresponding to the amino terminus of human IκBα protein.
This Cell Signaling Technology antibody is conjugated to biotin under optimal conditions. The biotinylated antibody is expected to exhibit the same species cross-reactivity as the unconjugated IκBα (L35A5) Mouse mAb (Amino-terminal Antigen) #4814.
The NF-κB/Rel transcription factors are present in the cytosol in an inactive state complexed with the inhibitory IκB proteins (1-3). Activation occurs via phosphorylation of IκBα at Ser32 and Ser36 followed by proteasome-mediated degradation that results in the release and nuclear translocation of active NF-κB (3-7). IκBα phosphorylation and resulting Rel-dependent transcription are activated by a highly diverse group of extracellular signals including inflammatory cytokines, growth factors, and chemokines. Kinases that phosphorylate IκB at these activating sites have been identified (8).
