Human IRF9 ELISA Kit (HUFI07765)

The interferon regulatory factor 9 protein functions as the DNA-binding component of the ISGF3 complex, partnering with STAT1 and STAT2 to drive type I interferon signaling. This quantitative immunoassay from Assay Genie is configured to measure human IRF9 in laboratory research samples, supporting investigations into antiviral defense, JAK-STAT pathway activation, cytokine responses, and disorders of innate immunity where interferon signaling is dysregulated.

Built around a standard microplate configuration, the kit provides enough reaction wells to run full standard curves alongside study specimens in a single batch. The format is supplied as a complete pack of reagents sufficient for 96 Assays, including pre-coated wells and the buffers needed for reproducible quantification. Unopened kits should be stored refrigerated; once opened, individual components are handled per the enclosed protocol to preserve activity across multiple runs.

Each kit is validated for use with human samples and is intended for research use only, making it a practical choice for cell culture supernatant analysis, lysates from IFN-stimulated cell lines, and work involving interferon pathway knock-out or knock-down models. Researchers studying hepatitis, influenza, SARS-CoV-2 host response, lupus-associated interferon signatures, or tumor immune microenvironment signaling rely on IRF9 quantification as part of broader panels examining interferon-stimulated gene expression.
