Used to detect and quantify levels of interleukin-33 (IL-33) in biological samples such as serum, plasma, and cell culture supernatants from mice. This kit is widely applied in immunology and inflammation research to study the role of IL-33 in allergic responses, asthma, autoimmune diseases, and immune regulation. It enables researchers to monitor disease progression and evaluate the effectiveness of therapeutic interventions in mouse models. The assay provides high sensitivity and specificity, making it suitable for measuring low concentrations of IL-33 in small sample volumes.
