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 helps in evaluating the effects of drugs or treatments on inflammatory markers and is widely used in neuroscience, oncology, and immunology studies involving rodent subjects. Its high sensitivity and specificity allow accurate quantification of IL-6 concentrations, supporting reliable data collection in experimental research.
