About InVivoSIM anti-human IFNAR1 (Anifrolumab Biosimilar) This non-therapeutic biosimilar antibody uses the same variable regions from the therapeutic antibody Anifrolumab making it ideal for research use. This Anifrolumab biosimilar reacts with human IFNAR1 (IFN alpha/beta receptor subunit 1). IFNAR-1 is coexpressed with IFNAR-2 on nearly all cell types and together these two subunits make up the heterodimeric Type I IFN Receptor complex. Type I IFNs (IFN-α/β) bind to the Type I IFN Receptor complex to induce cellular responses including induction of anti-viral, anti-microbial, anti-tumor, and autoimmune responses as well as to regulate the activation, proliferation, and differentiation of many cell types. Anifrolumab is used to treat systemic lupus erythematosus (SLE) in adults.
