Used in immunological research to quantify levels of CCL25, a chemokine involved in T-cell development and recruitment to the thymus and gut. Enables study of immune system regulation, inflammatory bowel disease, and mucosal immunity. Commonly applied in biomarker discovery, preclinical studies, and monitoring chemokine expression in cell cultures or biological fluids such as serum and tissue homogenates. Supports investigation into autoimmune disorders, cancer immunology, and therapeutic targeting of chemokine pathways.
