Used in research and development for targeting CCL2 (MCP-1), a chemokine involved in inflammatory and immune responses. It has been investigated in oncology for its potential to inhibit tumor growth and metastasis by blocking the recruitment of tumor-associated macrophages. Also studied in chronic inflammatory diseases such as fibrosis, atherosclerosis, and rheumatoid arthritis, where CCL2 plays a role in monocyte migration and disease progression. Serves as a reference standard in immunoassays and antibody development due to its high specificity and neutralizing activity.
