| Objective: To clone and construct the prokaryotic expression vector of the TNF-related apoptosis inducing ligand gene
（amino acids 114～281）. Methods: RNA was extracted from the peripheral blood of health adult. A pair of primers with restriction site
EcoR I/Xho I was designed. The extracellular domain region of TRAIL gene was amplified by RT-PCR and then cloned into the prokaryotic
expression vector pGEX-6P-1. The recombinants were confirmed by EcoR I/Xho I digestion, PCR, and DNA sequencing. Result:
The extracellular domain region with a molecular size of 501 bp of TRAIL gene was amplified successfully. DNA sequencing showed
that the recombinant plasmid was successfully constructed. Conclusion: A prokaryotic expression vector pGEX-6P-1/TRAIL was constructed
successfully, which provides theory for tumor apoptosis research. |
