Anti-IRF9 Antibody

The Anti-IRF9 polyclonal reagent from Antibodies.com is a rabbit IgG primary antibody raised against human Interferon Regulatory Factor 9, supplied unconjugated in a 100 µl vial format optimized for western blot workflows.

IRF9, also designated ISGF3G or p48, partners with phosphorylated STAT1 and STAT2 to assemble the ISGF3 transcription complex that drives type I interferon-dependent gene expression. It is therefore a focal target in studies of antiviral restriction, JAK-STAT signaling, and innate immune regulation in human cells.

Validated for WB on human samples, the antibody is provided as an unconjugated polyclonal reagent that researchers can pair with HRP or fluorophore-conjugated secondary reagents of their choice. Aliquoting upon receipt and limiting freeze-thaw cycles helps preserve antigen-binding activity over multiple experiments.

This reagent supports detection of endogenous IRF9 in cell lysates, characterization of interferon-stimulated gene (ISG) induction, and dissection of type I IFN pathway activation in viral infection models and immunoblotting-based signaling studies.
