Objective To construct the human interleukin 18 DNA plasmids vaccine and to express the eukaryotic plasmids vaccine in mammalian cell lines Cos 7 and D5.Methods Gene recombinant technique was used to construct hIL 18 eukaryotic expression vectors.Calcium phosphate method was performed to transect recombinant hIL 18 eukaryotic expression vectors into Cos 7 and D5 cells. In situ hybridization and Western Blot were implemented to verify the transient expression of recombinant hIL 18 in Cos 7 and D5.Results The eukaryotic expression plasmid pVAX1 IL 18 was constructed successfully.hIL 18 was transiently expressed in Cos 7 and D5.Conclusion The eukaryotic expression plasmid pVAX1 IL 18 was constructed. In situ hybridization and Western Blot results proved the successful transient expression of pVAX1 IL 18 in Cos 7 and D5.Therefore,the work has settled the foundation for further biological research on hIL 18,including immunogene therapy through hIL 18.
