Used to measure interleukin-6 (IL-6) levels in biological samples such as serum, plasma, or cell culture supernatants from rats. It is commonly applied in research settings to study inflammation, immune responses, and disease progression in rat models. The kit enables accurate quantification of IL-6, helping in the evaluation of therapeutic interventions, infection studies, and autoimmune disease research. Due to its high sensitivity and specificity, it is a reliable tool for detecting low concentrations of IL-6 in small sample volumes.
