The MCP proteins belong to the CC chemokine family, and signal through CCR2 and, with the exception of MCP-1, other CCR receptors. The MCP proteins chemoattract and activate monocytes, activated T cells, basophils, NK cells, and immature dendritic cells. The MCP family cross- reacts across species. Recombinant murine MCP-5 is a 9.3 kDa protein containing 82 amino acid residues including the four highly conserved cysteine residues present in the CC chemokines. MW: 9.3 kDa. Purity ≥98%
