Used to measure levels of CCL22 (also known as MDC – Macrophage-Derived Chemokine) in human biological samples such as serum, plasma, or cell culture supernatants. This assay is commonly applied in immunology and inflammation research to study immune cell recruitment, particularly the activation and migration of dendritic cells, T cells, and regulatory T cells. It is also used in studies related to allergic diseases, autoimmune disorders, cancer immunology, and infectious diseases where CCL22 plays a role in modulating immune responses. The kit enables quantitative detection, supporting both clinical research and drug development efforts targeting chemokine pathways.
