Upon recognizing viral RNA, RIG-I signals through the adaptor MAVS to activate transcription factors that induce type I interferons. Secreted interferons then act through the JAK\/STAT pathway to assemble the ISGF3 complex, which binds interferon-stimulated response elements (ISRE) in the promoters of antiviral genes. The ISRE element therefore reports the output of RIG-I-initiated innate immune signaling, making RIG-I a key target in antiviral immunity and interferon biology research.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eProduct Description \u0026amp; Applications\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThe RIG-1\/ISRE Reporter Lentivirus Set is an immunotherapy reporter system supplied as two vials. A receptor lentivirus constitutively expresses human RIG-I with antibiotic selection, while a reporter lentivirus carries tandem ISRE response elements driving a dual reporter, secreted Gaussia luciferase together with eGFP or mCherry. Sequential transduction and selection generates a dual-stable cell line that produces a quantitative readout when RIG-I-initiated signaling activates ISRE-dependent transcription.\u003c\/p\u003e\n\u003cp\u003eSecreted Gaussia luciferase accumulates in conditioned media, allowing kinetic sampling without cell lysis, while fluorescence supports microscopy and flow cytometry. The VSV-G-pseudotyped particles are purified by PEG precipitation and sucrose gradient centrifugation and transduce difficult-to-transfect cells, including primary and thawed cultures. The system supports antiviral innate immunity assays and study of interferon signaling.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eAbout This Product\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThis 2-vial immunotherapy reporter system consists of a \u003cstrong\u003eVial 1 Receptor Lentivirus\u003c\/strong\u003e encoding human RIG-1 under a constitutive promoter with antibiotic selection, and a \u003cstrong\u003eVial 2 Reporter Lentivirus\u003c\/strong\u003e encoding tandem NFAT (or NF-κB) response elements driving a dual reporter (Gaussia Luciferase + eGFP, Gaussia Luciferase + mCherry).
