Used to measure levels of interleukin-1 in biological samples such as serum, plasma, or cell culture supernatants. Widely applied in immunology and inflammation research to study immune responses, autoimmune diseases, and infectious conditions. Helps evaluate cytokine production in mouse models, supporting drug development and mechanistic studies in preclinical trials. Provides quantitative data with high sensitivity and specificity, enabling accurate assessment of IL-1 expression under experimental conditions.
