Abstract：Objective To construct the eukaryotic expression plasmid of human cannabinoid receptor 2 ( hCB2) gene GV230 and to detect the expression of hCB2 gene in the HEK293 cells.Methods Full length of hCB2 cDNA was obtained by RT-PCR with total RNA isolated from human T lymphocytes, and then we inserted the target fragment into eukaryotic ex-pression vector GV230 to construct the recombinant expression plasmid GV230-hCB2 after enzyme digestion, connection and sequencing.We used the liposome to transiently transfect HEK293 cells.The expression of hCB2 gene expression products was detected by Western blotting and confocal laser scanning microscope (CLSM).Results The hCB2 gene fragments were amplified, and we successfully constructed the recombinant expression plasmid, detected the target protein expressing in the transfected cells, and observed the distribution and expression of hCB2 receptor in the cell membrane. Conclusion We successfully contrast the GV230-hCB2 plasmid expressing hCB2 protein in the HEK293 cells, which lays the experimental foundation for further research of hCB2 biology function.
