Used to measure levels of interleukin-1β (IL-1β) in human biological samples such as serum, plasma, or cell culture supernatants. It is commonly applied in research and clinical settings to study inflammatory diseases including rheumatoid arthritis, type 2 diabetes, and inflammatory bowel disease. The kit enables precise quantification of IL-1β, helping researchers assess immune response activation, evaluate drug efficacy in anti-inflammatory therapies, and monitor disease progression. Widely used in immunology, oncology, and neuroscience research due to the central role of IL-1β in inflammation and host defense.
