Used to measure interleukin-6 (IL-6) levels in human biological samples such as serum, plasma, or cell culture supernatants. It is widely applied in clinical research and diagnostics to study inflammatory conditions, autoimmune diseases, infections, and cancer. The kit enables accurate quantification of IL-6, helping in monitoring disease progression and evaluating treatment responses. Commonly used in laboratories for biomarker analysis and in studies related to immune system activity.
