Used in research to measure levels of Eotaxin-1 (CCL11) in biological samples such as serum, plasma, or cell culture supernatants. This ELISA kit helps study eosinophil recruitment in allergic diseases like asthma, eczema, and allergic rhinitis. It is also applied in inflammation and immune response studies, particularly in conditions involving eosinophilia. Researchers use it to evaluate the effectiveness of anti-inflammatory or anti-allergic drugs by monitoring changes in Eotaxin-1 concentration. The kit provides a sensitive and specific way to quantify this chemokine, supporting investigations in immunology, respiratory diseases, and therapeutic development.
