Used in biomedical research to measure levels of thymus stromal lymphopoietin (TSLP) in human biological samples such as serum, plasma, or cell culture supernatants. TSLP is a cytokine involved in allergic inflammation and immune responses, particularly in conditions like asthma, atopic dermatitis, and other allergic diseases. The ELISA kit enables researchers to quantify TSLP expression to study its role in disease mechanisms, evaluate therapeutic interventions, and assess immune system activation in clinical and preclinical studies. It is widely used in immunology labs, pharmaceutical development, and diagnostic research.
