Used in immunological research to quantitatively measure CCL17 levels in biological samples such as serum, plasma, and cell culture supernatants. Helps in studying inflammatory diseases, allergic responses, and immune system activation. Commonly applied in research on asthma, atopic dermatitis, and certain cancers where CCL17 plays a role in recruiting immune cells. Supports biomarker discovery and evaluation of therapeutic efficacy in clinical and preclinical studies.
