Used in immunological research to quantify levels of CCL26 (Eotaxin-3) in biological samples such as serum, plasma, or cell culture supernatants. This ELISA kit helps investigate the role of CCL26 in eosinophil recruitment and activation, particularly in allergic diseases like asthma, atopic dermatitis, and eosinophilic esophagitis. It is also applied in studies of inflammatory responses and immune cell trafficking, supporting biomarker discovery and evaluation of therapeutic interventions targeting chemokine pathways.
