Used in biomedical research to detect and quantify interleukin-11 (IL-11) levels in rat biological samples such as serum, plasma, and cell culture supernatants. This ELISA kit is particularly valuable in studies related to inflammation, immune response, hematopoiesis, and tissue regeneration. It enables researchers to monitor IL-11 expression in experimental models of diseases like arthritis, fibrosis, and certain cancers. The assay provides high specificity and sensitivity, supporting accurate measurement of cytokine levels for reliable data in preclinical research and drug development.
