IFNAR Antibody

Anti-IFNAR1 Antibody (Anifrolumab) is a humanized IgG1 kappa monoclonal antibody targeting the type I interferon receptor subunit 1 (IFNAR1) . This product specifically binds to IFNAR1, blocking the interaction of all type I interferons (including all subtypes of IFN-alpha, IFN-beta, and IFN-omega) with the receptor complex. This inhibition blocks the activation of the downstream JAK/STAT signaling pathway, reduces the expression of interferon-stimulated genes (ISGs), and suppresses type I interferon-mediated immune responses.
