Used in immunological research to quantify MDC (Macrophage-Derived Chemokine), also known as CCL22, secreted by human macrophages. This ELISA kit enables researchers to measure CCL22 levels in cell culture supernatants, serum, or plasma, supporting studies on immune cell recruitment, inflammation, allergic responses, and autoimmune diseases. It is particularly valuable in cancer research, as CCL22 plays a role in attracting regulatory T cells to tumor microenvironments, influencing immune evasion. The kit provides a reliable and sensitive method for monitoring chemokine expression in human samples, aiding in biomarker discovery and therapeutic development.
