Used in immunological research to quantify mouse interleukin-3 (IL-3) levels in biological samples such as serum, plasma, or cell culture supernatants. This ELISA kit enables researchers to study the role of IL-3 in hematopoiesis, immune cell activation, and inflammatory responses. It is commonly applied in studies involving allergic reactions, autoimmune diseases, and bone marrow cell development. The assay provides high sensitivity and specificity, making it suitable for monitoring cytokine production in experimental models of infection, inflammation, or drug treatment.
