Product Information
Product Usage Information
This product is the carrier free version of product #98344. All data were generated using the same antibody clone in the standard formulation which contains BSA and glycerol.
This formulation is ideal for use with technologies requiring specialized or custom antibody labeling, including fluorophores, metals, lanthanides, and oligonucleotides. It is not recommended for ChIP, ChIP-seq, CUT&RUN or CUT&Tag assays. If you require a carrier free formulation for chromatin profiling, please contact us. Optimal dilutions/concentrations should be determined by the end user.
BSA and Azide Free antibodies are quality control tested by size exclusion chromatography (SEC) to determine antibody integrity.

Storage
Store at -20°C. This product will freeze at -20°C so it is recommended to aliquot into single-use vials to avoid multiple freeze/thaw cycles. A slight precipitate may be present and can be dissolved by gently vortexing. This will not interfere with antibody performance.
Specificity / Sensitivity
IRF-8 (E8X4K) Rabbit mAb (BSA and Azide Free) recognizes endogenous levels of total IRF-8 protein.
Species Reactivity:
Human, Mouse, Rat
Source / Purification
Monoclonal antibody is produced by immunizing animals with recombinant protein specific to the amino terminus of human IRF-8 protein.
Background
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).
IRF-8/ICSCP is expressed predominately in hematopoietic cells and is further increased upon treatment with interferon (3,4). IRF-8 can function as a transcription repressor of ICS-containing promoters (4). Expression of IRF-8 can lead to the downregulation of the anti-apoptotic protein Bcl-2 (5). Originally described as being induced by IFN-γ, IRF-8 expression is also elevated by IRF-α as well as IL-12 in NK and T cells (6). IRF-8 deficient mice have enhanced susceptibility to various pathogens and impaired production of interferons, as well as deregulated hematopoiesis that resembles chronic myelogenous leukemia (7,8). IRF-8 also regulates bone metabolism by suppressing osteoclast formation (9).
