Used in immunological research to quantify levels of MDC/CCL22, a chemokine involved in immune cell recruitment, particularly dendritic cells and T cells, to sites of inflammation or infection. The ELISA kit enables precise measurement of MDC/CCL22 in biological samples such as serum, plasma, and cell culture supernatants. It is widely applied in studies related to allergic diseases, autoimmune disorders, cancer immunology, and inflammatory conditions to understand chemokine dynamics and immune response modulation. The assay supports high sensitivity and specificity, making it suitable for both basic research and preclinical evaluation of therapeutic agents targeting chemokine pathways.
