| Background | Interferon regulatory factors (IRFs) comprise a family of transcription factors that function within the Jak/Stat pathway to regulate interferon (IFN) and IFN-inducible gene expression in response to viral infection. IRFs play an important role in pathogen defense, autoimmunity, lymphocyte development, cell growth, and susceptibility to transformation. The IRF family includes nine members: IRF-1, IRF-2, IRF-9/ISGF3γ, IRF-3, IRF-4 (Pip/LSIRF/ICSAT), IRF-5, IRF-6, IRF-7, and IRF-8/ICSBP. All IRF proteins share homology in their amino-terminal DNA-binding domains. IRF family members regulate transcription through interactions with proteins that share similar DNA-binding motifs, such as IFN-stimulated response elements (ISRE), IFN consensus sequences (ICS), and IFN regulatory elements (IRF-E). IRF-3 can inhibit cell growth and plays a critical role in controlling the expression of genes in the innate immune response. In unstimulated cells, IRF-3 is present in the cytoplasm. Viral infection results in phosphorylation of IRF-3 and leads to its translocation to the nucleus where it activates promoters containing IRF-3-binding sites. Phosphorylation of IRF-3 occurs at a cluster of C-terminal serine and threonine residues (between 385 and 405) leading to its association with the p300/CBP coactivator protein that promotes DNA binding and transcriptional activity. During infection, IRF-3 is likely activated through a pathway that includes activation of Toll-like receptors and of a kinase complex that includes IKKε and TBK1. IRF-3 is phosphorylated at Ser396 following viral infection, expression of viral nucleocapsid, and double stranded RNA treatment. These events likely play a role in the activation of IRF-3. |

保存條件：
IRF3 Rabbit Polyclonal Antibody (KO Validated) -20ºC保存，Western一抗稀釋液-20ºC或4ºC保存，一年有效。Western一抗稀釋液優先推薦4ºC保存，長期不使用可以考慮-20ºC保存，但凍融可能會導致出現輕微的渾濁和少量不溶物。
注意事項：
如果本抗體用于Western blot (WB)、免疫熒光(IF)、免疫細胞化學(ICC)等實驗，請注意回收使用過的稀釋抗體。回收的抗體通常至少可以重復使用5-10次。稀釋后的抗體，包括已經使用過的稀釋抗體，請4℃保存。
回收后重復使用的抗體，使用方法同新鮮稀釋的抗體。如果在重復使用過程中發現抗體出現輕微混濁現象，可以10,000g離心1-3分鐘，取上清用于后續檢測。如果回收的抗體出現明顯的絮狀物或長霉長菌等情況，則可以考慮廢棄該抗體。
提供的Western一抗稀釋液也可以用于免疫熒光(IF)、免疫組化(IHC)、免疫細胞化學(ICC)等適當用途。如果希望獲得最佳的檢測效果，請考慮使用上述檢測專用的一抗稀釋液。
