Used in immunological research to quantify levels of Monocyte Chemotaxis Protein-4 (MCP-4/CCL13) in biological samples such as serum, plasma, and cell culture supernatants. This ELISA kit enables researchers to study the role of MCP-4 in inflammatory processes, allergic responses, and immune cell recruitment. It is commonly applied in studies related to asthma, atherosclerosis, and autoimmune diseases where chemokine activity influences disease progression. The assay provides a sensitive and specific means to measure protein expression, supporting biomarker discovery and evaluation of therapeutic interventions targeting inflammatory pathways.
