Used to measure levels of MCP-1 (monocyte chemotactic protein-1) in human biological samples such as serum, plasma, or cell culture supernatants. It is widely applied in research related to inflammation, autoimmune diseases, atherosclerosis, and cancer, where MCP-1 plays a key role in recruiting monocytes to sites of tissue damage or infection. The kit enables accurate quantification of MCP-1 concentration, supporting studies on disease progression, immune response, and therapeutic efficacy in clinical and preclinical settings.
