IMPORTANT: Sodium azide forms explosive compounds with heavy metals. These products contain <0.05% (w/w) azide which with repeated contact with lead and copper commonly found in plumbing drains may result in the buildup of shock sensitive compounds. Dispose in accordance with regulations from your institute.

Chemokine (C-C motif) ligand 8, also known as monocyte chemoattractant protein 2 (MCP-2) and small inducible cytokine A8 (SYCA8), is a small cytokine belonging to the CC chemokine family. The CCL8 protein is produced as a precursor containing 109 amino acids, which is cleaved to produce mature CCL8 containing 75 amino acids. The gene for CCL8 is encoded by 3 exons and is located within a large cluster of CC chemokines on chromosome 17q11.2 in humans. MCP-2 is chemotactic for and activates a many different immune cells, including mast cells, eosinophils and basophils, (that are implicated in allergic responses), and monocytes, T cells, and NK cells that are involved in the inflammatory response. CCL8 elicits its effects by binding to CCR1, CCR2B and CCR5 chemokine receptors. MCP-2 is a potent inhibitor of HIV-1 by virtue of its high-affinity binding to the receptor CCR5, one of the major co-receptors for HIV-1.
