Anti-IRF9 Antibody

Affinity-purified from rabbit serum, this unconjugated polyclonal IgG reagent is raised against human Interferon Regulatory Factor 9 (IRF9), also known as ISGF3G and p48, the DNA-binding subunit of the ISGF3 complex that drives type I interferon-stimulated gene transcription alongside STAT1 and STAT2. Antibodies.com supplies the antibody as a 50 µl liquid aliquot validated for western blot detection of endogenous IRF9 in human cell and tissue lysates, with HRP- or fluorophore-conjugated secondary reagents enabling clear chemiluminescent or fluorescent readouts. Suggested starting applications include probing JAK-STAT signaling, dissecting antiviral response pathways, and characterizing interferon-stimulated gene regulation in innate immunity and viral pathogenesis models. The polyclonal format offers multi-epitope recognition, useful when IRF9 expression is low or when monitoring full-length versus truncated isoforms. Shipped on cold gel packs; for long-term storage, aliquot and freeze at -20°C and protect from repeated freeze-thaw cycles.
