Description: The 5D3-F7 antibody reacts with human, cynomolgus, and rhesus monkey monocyte chemoattractant protein-1 (MCP-1), also known as monocyte chemotactic and activating factor (MCAF) and CCL2. MCP-1 is a CC chemokine which presents as a dimer. Derived from monocytes and vascular endothelial cells, it exerts chemoattractant activity on a variety of cell types, such as monocytes, basophils, T cells and NK cells via chemokine receptors such as CCR2, CCR5, and CCR10.
