Specifications for IFN-α Antibody, anti-human, REAfinity™


Type I interferons (IFNs), including IFN-α, are a family of cytokines that exert pleiotropic functions in the immune system. Besides its potent antiviral activity, IFN-α exerts a variety of immunomodulatory effects, including positive and negative regulation of its own production, regulation of IL-12 and IFN-γ production, promotion of natural killer (NK) cell cytotoxicity, activation and maturation of dendritic cells, and the promotion of B cell development towards plasma cells. IFN-α is expressed predominantly by CD123+CD11c-CD303 (BDCA2)+ plasmacytoid dendritic cells (pDCs). Clone REA1013 recognizes the majority of the IFN-α subtypes, including IFN-α2b.
Additional information: Clone REA1013 displays negligible binding to Fc receptors.
