Used in the treatment of autoimmune and inflammatory diseases by targeting and neutralizing interleukin-6 (IL-6), a key cytokine involved in inflammation and immune response. This antibody helps reduce chronic inflammation in conditions such as rheumatoid arthritis, lupus, and cytokine release syndrome. It is also investigated for use in certain cancers where IL-6 plays a role in tumor growth and immune evasion. Due to its high specificity, it serves as a reference standard in bioassays and drug development for evaluating the efficacy of anti-IL-6 therapies.
