Used in immunological research to quantify levels of MCP-2/CCL8 in biological samples such as serum, plasma, and cell culture supernatants. Enables study of inflammatory responses, immune cell recruitment, and chemokine activity in mouse models. Commonly applied in research on autoimmune diseases, infections, and cancer to assess monocyte and lymphocyte migration mechanisms. Supports high-throughput screening and validation of therapeutic targets involving chemokine signaling pathways.
