{"product_id":"biolegend-660702","title":"Biolegend, 660702, Purified anti-IRF9 Antibody, 100μg","description":"\u003cp\u003eIRF9 is a member of the IRF family of transcription factors and plays an important role in IFN signaling pathways and anti-viral immune responses. Type I and type III interferon stimulation induces phosphorylation and heterodimerization of STAT1 and STAT2. The activated STAT1:STAT2 heterodimer recruits IRF9 and forms a heterotrimeric complex termed IFN-stimulated gene factor 3 (ISGF3). The ISGF3 complex, in turn, translocates to the nucleus and transactivates IFN-inducible genes. The IRF9 protein in the ISGF3 complex is responsible for the recognition of IFN-stimulated response elements (ISRE). Mice lacking IRF9 fail to induce the expression of IFN regulated genes in response to type I interferon stimulation, indicating that IRF9 is crucial in mediating interferon signaling.\u003cbr\u003e\n100μg\u003cbr\u003e\nVerified Reactivity: Human\u003cbr\u003e\nAntibody Type: Monoclonal\u003cbr\u003e\nHost Species: Mouse\u003cbr\u003e\nImmunogen: Partial human IRF9 recombinant protein (116-387 a.a.) expressed in E. coli.\u003cbr\u003e\nFormulation: This antibody is provided in phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide.\u003cbr\u003e\nPreparation: Affinity purified.\u003cbr\u003e\nConcentration: 0.5 mg\/mL\u003cbr\u003e\nStorage \u0026amp; Handling: Upon receipt, store undiluted 2°C and 8°C.\u003cbr\u003e\nApplication: WB - Quality tested ICC, ChIP - Verified\u003cbr\u003e\nRecommended Usage: Each lot of this antibody is quality control tested by Western blotting.
