Monocyte chemotactic protein 3 (MCP-3) is now renamed as chemokine (C-C motif) ligand 7 (CCL7), recently purified from human osteosarcoma cell line and is a novel chemokine. Due to the fact that CCL7 contains two adjacent N-terminal cysteine residues in its mature protein, it is classified as a CC chemokines subfamily member. MCP-3 has the ability to bind and activate a large number of diverse inflammatory cell types via the interaction with multiple leukocyte receptors as well as it’s own receptor. Evidence indicates that MCP-3 does indeed use multiple receptors (which includes MCP-1, MIP-1a, RANTES) and can also bind with MIP-1ß receptor as well as other unique binding sites. CCL7 can specifically attracts monocytes and regulates macrophage function. CCL7 has been shown to interact with MMP2.
cDNA cloning of MCP-3 and structural analysis has revealed that it composed of 76 amino acid polypeptide with a molar mass of 8.5 kDa. It is part of a small family of inflammatory proteins that can be characterized by four conserved cysteine residues and it is located on the human chromosome 17. MCP-3 and MCP-1 display 71% a.a. homology, whilst it is also revealed to have 30% a.a homology with RANTES and MIP-1 and these all can activate T-cells, basophils, monocytes and eosinophils. MCP-3 can also promote the exocytosis of eosinophil granule proteins and stimulates the release of histamine from human basophils.
MCP-3 ELISA kit can be used to determine in vitro quantitative levels of monocyte chemotactic protein 3 (MCP-3)(CCL7) in human serum, plasma, cell culture supernatant and many other biological fluids. This assay has a minimum detection limit of < 30.0 pg/ml.
The minimum detection sensitivity level of MCP-3 (CCL7) using this human MCP-3 ELISA kit was 30.0 pg/ml. The dynamic assay range for this kit is 30.0 – 1,600 pg/ml.
