Used in immunological research to quantify levels of Thymic Stromal Lymphopoietin (TSLP) in biological samples such as serum, plasma, and cell culture supernatants. This kit enables researchers to study the role of TSLP in allergic diseases including asthma, atopic dermatitis, and allergic rhinitis. It is also applied in investigating inflammatory and autoimmune conditions where TSLP contributes to immune dysregulation. The assay supports drug development and preclinical studies by providing a reliable method to monitor TSLP expression in response to therapeutic interventions.
