Used to measure levels of interleukin-5 (IL-5) in biological samples such as serum, plasma, or cell culture supernatants. IL-5 is a cytokine involved in the activation, growth, and differentiation of eosinophils, making this kit valuable in immunology and inflammation research. Commonly applied in studies related to allergic diseases, asthma, parasitic infections, and autoimmune conditions. Provides a reliable and sensitive method for quantifying IL-5 in rabbit models, supporting preclinical research and development of therapeutic interventions targeting the IL-5 pathway.
