Neutralizing IgG monoclonal antibody to human interferon-beta

Neutralizing monoclonal antibody against human IFN-β
Neutralizing monoclonal antibody against human IFN-β

Anti-hIFN-β-IgG (clone 10B10) is a monoclonal antibody for human interferon β (hIFN-β). This antibody has been produced in hybridomas and purified by affinity chromatography.
Anti-hIFN-β-IgG has been selected for its ability to efficiently neutralize the biological activity of hIFN-β. IFN-β is an important anti-viral cytokine that also has anti-proliferative and immunomodulatory functions [1, 2].

Details

Type I interferons, in particular interferon-alpha (IFN-α) and interferon beta (IFN-β), play a vital role in host resistance to viral infections [1, 2]. The type I IFN family is a multi-gene cytokine family that encodes 13 partially homologous IFN-α subtypes in humans (14 in mice), a single IFN-β, and several poorly defined single gene products (IFN-ɛ, IFN-τ, IFN-κ, IFN-ω, IFN-δ, and IFN-ζ) [1, 2].  IFN-α and IFN-β are the best-defined and most broadly expressed type I IFNs [2].

IFN-β and all of the IFN-α subtypes bind to a heterodimeric transmembrane receptor composed of the subunits IFNAR1 and IFNAR2 which are associated with the tyrosine kinases Tyk2 and Jak1 (Janus kinase 1) respectively. These kinases phosphorylate STAT1 and STAT2 which then dimerize and interact with IFN regulatory factor 9 (IRF9), leading to the formation of the ISGF3 complex. ISGF3 binds to IFN-stimulated response elements (ISRE) in the promoters of IFN-stimulated genes (ISG) to regulate their expression.
