[Construction and identification of tetracycline-inducible human hepatocyte growth factor eukaryotic expression vector].

OBJECTIVE

To construct a tetracycline-inducible eukaryotic expression vector containing human hepatocyte growth factor (HGF) cDNA.

METHODS

Human HGF cDNA fragment was obtained by PCR from pUC-SRalpha/HGF plasmid and inserted into the restriction site between Mlu I and Sal I of the tetracycline-inducible eukaryotic expression vector pBI-L. pBI-L-HGF was constructed by DNA recombination in vitro, and was identified by restriction endonucleases digestion and sequencing.

RESULTS

The fragment of pBI-L-HGF digested with restriction endonucleases well corresponded to expectation, and the sequence of inserted HGF cDNA was correct according to the GenBank.

CONCLUSION

The tetracycline-inducible eukaryotic expression vector of human HGF pBI-L-HGF has been constructed successfully, which allows further study of HGF gene therapy with much safety and easy manipulation.
