Objective: To clone and express human monocyte chemoattractant protein-1 (huMCP-1 ) with important biologic functions. Methods: Poly (A)~+ RNA was extracted from PBMC and huMCP-1 cDNA was obtained by RT-PCR. huMCP-1 cDNA was inserted into fusion expression vector pGEXIN site of BamH I,QD and EcoR I,and gained high expres- sion induced by 1 mmol/L IPTG. Results: Western blotting analysis showed that the product had apparent cross reaction with huMCP-1 monoclonal antibody. Conclusion: Success on cloning and expression of huMCP-1 provide useful material for the laboratory and clinic research of MCP-1.
