Clone Host Grade Applications
Polyclonal Rabbit Affinity Purified B
Interferons (IFN)s are involved in a multitude of immune interactions during viral infections and play a major role in both the induction and regulation of innate and adaptive antiviral mechanisms. During infection, host-virus interactions signal downstream molecules such as transcription factors such as IFN regulatory factor-3 (IRF3) which can act to stimulate transcription of IFN-a/b genes. IRF3 is present in an inactive form in the cytoplasm of most cells. Following viral infection, IRF3 can be activated by IkB kinase-e and TANK-binding kinase 1 (TBK1), whereupon IRF3 translocates to the nucleus. IRF3 can also be activated by stimulation of toll-like receptor 3 (TLR3) by dsRNA. IRF3 exists as at least two distinct isoforms.
Catalog #I7662-85B
ApplicationsSuitable for use in Western Blot. Other applications not tested.
Recommended DilutionWestern Blot: 0.5-2ug/ml of this lot detected phospho-IRF-3
(Ser396) in RIPA lysates from vesicular stomatitis virus (VSV) infected A549 cells. Untreated A549 cell lysate and VSV infected A549 cell lysate were resolved by electrophoresis, transferred to nitrocellulose and probed with I7662-85B
(0.5ug/ml). Proteins were visualized using an IgG (HRP) goat anti-rabbit and a chemiluminescence detection system.
Optimal dilutions to be determined by the researcher.
