IRF3 Antibody (712217) in ICC/IF
For immunofluorescence analysis, A549 cells were fixed and permeabilized for detection of endogenous IRF3 using Anti-IRF3 Recombinant Rabbit Superclonal™ Antibody (Product # 712217, 1:100 dilution) and labeled with Goat anti-Rabbit IgG (Heavy Chain) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A27034, 1:2000). Nuclei (blue) were stained using ProLong™ Diamond Antifade Mountant with DAPI (Product # P36962) and cytoskeletal F-actin (red) staining using Rhodamine Phalloidin (Product # R415, 1:300) Panel a-d) shows re...

Product Specific Information
This antibody is predicted to react with Monkey, Cat, Bat.
Recombinant rabbit Superclonal™ antibodies are unique offerings from Thermo Fisher Scientific. They are comprised of a selection of multiple different recombinant monoclonal antibodies, providing the best of both worlds - the sensitivity of polyclonal antibodies with the specificity of monoclonal antibodies - all delivered with the consistency only found in a recombinant antibody. While functionally the same as a polyclonal antibody - recognizing multiple epitope sites on the target and producing higher detection sensitivity for low abundance targets - a recombinant rabbit Superclonal™ antibody has a known mixture of light and heavy chains. The exact population can be produced in every lot, circumventing the biological variability typically associated with polyclonal antibody production. Note: Formerly called “Recombinant polyclonal antibody”, this product is now rebranded as “Recombinant Superclonal™ antibody”. The physical product and the performance remain unchanged.
Target Information
IFR3 (interferon regulatory factor 3) is a key transcriptional regulator of type I interferon (IFN)-dependent immune responses. It plays a critical role in the innate immune response against DNA and RNA viruses. IFR3 regulates the transcription of type I IFN genes (IFN-alpha and IFN-beta) and IFN-stimulated genes (ISG) by binding to an interferon-stimulated response element (ISRE) in their promoters. It acts as a more potent activator of the IFN-beta gene than the IFN-alpha gene and plays a critical role in both the early and late phases of the IFNA/B gene induction. IFR3 is found in an inactive form in the cytoplasm of uninfected cells and following viral infection, double-stranded RNA, or toll-like receptor signaling. It is phosphorylated by IKBKE and TBK1 kinases. This induces a conformational change, leading to its dimerization and nuclear localization and association with CREB binding protein to form dsRNA-activated factor 1 (DRAF1), a complex which activates the transcription of the type I IFN and ISG genes. Mutations in the gene can result in encephalopathy, acute, infection-induced, herpes-specific 7.
