Used to quantitatively measure RANTES/CCL5 levels in human biological samples such as serum, plasma, or cell culture supernatants. This ELISA kit is widely applied in immunology and inflammation research, helping assess immune cell activation and chemokine activity. It is particularly useful in studies related to autoimmune diseases, HIV infection, allergic responses, and cancer, where RANTES plays a role in recruiting immune cells to sites of inflammation or disease. The assay provides high sensitivity and specificity, enabling accurate detection of low concentrations of RANTES, which supports both clinical research and drug development.
