Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Pro362 of human IRF-9 protein.

Western Blotting

Western Blotting

Western blot analysis of extracts from various cell lines using IRF-9 (D8G7H) Rabbit mAb.

Western Blotting

Western Blotting

Western blot analysis of extracts from HeLa cells, untreated (-) or treated with Human Interferon-α1 (hIFN-α1) #8927 (10 ng/ml, 16 hr; +), using IRF-9 (D8G7H) Rabbit mAb (upper) and β-Actin (D6A8) Rabbit mAb #8457 (lower).



Immunoprecipitation of IRF-9 from THP-1 cell extracts. Lane 1 is 10% input, lane 2 is Rabbit (DA1E) mAb IgG XP® Isotype Control #3900, and lane 3 is IRF-9 (D8G7H) Rabbit mAb. Western blot analysis was performed using IRF-9 (D8G7H) Rabbit mAb.


Interferon regulatory factors (IRFs) comprise a family of transcription factors that function within the Jak/Stat pathway to regulate interferon (IFN) and IFN-inducible gene expression in response to viral infection (1). IRFs play an important role in pathogen defense, autoimmunity, lymphocyte development, cell growth, and susceptibility to transformation. The IRF family includes nine members: IRF-1, IRF-2, IRF-9/ISGF3γ, IRF-3, IRF-4 (Pip/LSIRF/ICSAT), IRF-5, IRF-6, IRF-7, and IRF-8/ICSBP. All IRF proteins share homology in their amino-terminal DNA-binding domains. IRF family members regulate transcription through interactions with proteins that share similar DNA-binding motifs, such as IFN-stimulated response elements (ISRE), IFN consensus sequences (ICS), and IFN regulatory elements (IRF-E) (2).

In response to type I interferons (e.g., IFN-α, IFN-β), interferon regulatory factor 9 (IRF-9, ISGF3γ) assembles into a protein complex with Stat1 and Stat2 and translocates to the nucleus where it induces transcription of interferon response genes by binding to ISREs (3,4). Expression of IRF-9 is also induced by type I interferons (5).
