Used to measure levels of interleukin-1β (IL-1β) in biological samples such as serum, plasma, or cell culture supernatants from rats. It is commonly applied in inflammation research to study immune responses, infectious diseases, and autoimmune conditions. The kit enables accurate quantification of IL-1β, helping assess the activation of inflammatory pathways in experimental models. It is widely used in preclinical studies to evaluate the effectiveness of anti-inflammatory drugs or treatments targeting cytokine production.
