Q: I performed Western blot with NFkB p65 Antibody (NB100-2176) using brain and liver tissues extracts. My question: is it possible that NF-kB-Ikb complex could be detected by this antibody? Because I found 2 bands in the Western blot results, one is located at 65 and the other above 100 kD.

A: It possible that NB100-2176 could detect the entire NFkB complex in addition to just the p65 protein. If your samples were not completely reduced and denatured, they could have remained bound in your gel. The band above 100 kDa could also be an aggregate of NFkB. You may consider probing that same membrane for a different NFkB complex protein that you would expect to remain bound under these conditions. A negative signal in this case would tell you that it's an aggregate of NFkB, or maybe that it's a non-specific band. Did you run a negative control?

Background: RelA/NFkB p65

p65 is a subunit of the nuclear factor kappa B. The transcription factor NFkB is widely recognized as a critical mediator of immune and inflammatory responses. In most cell types, NFkB is found in the cytoplasm where it is associated with an inhibitory protein known as IkB. An impressive variety of stimuli (tumor necrosis factor, interleukin 1, T cell activation signals, bacterial endotoxins, viral transforming proteins, certain growth factors and reactive oxygen intermediates) lead to the rapid nuclear accumulation of NFkB by the induced phosphorylation and subsequent degradation of IkB. In the nucleus, NFkB regulates genes encoding cytokines, cytokine receptors, cell adhesion molecules, proteins involved in coagulation and genes involved in cell growth control. Additionally, NFkB is thought to be an important transcriptional regulator for HIV. Growing evidence indicates that the dysregulation of NFkB may be key to a number of diseases including arthritis and other inflammatory diseases, Alzheimer's disease, atherosclerosis and cancer.
