Used in research and development for autoimmune diseases, particularly systemic lupus erythematosus (SLE). It neutralizes the activity of interferon-alpha (IFN-α), a key cytokine involved in the inflammatory response seen in lupus. By inhibiting IFN-α signaling, it helps reduce disease activity and is studied as a potential therapeutic agent in patients with high interferon signatures. Also serves as a reference standard in immunoassays and bioassays to evaluate the potency and specificity of other anti-IFN-α antibodies.
