Abstract:
Objective To construct the human interleukin-18(hIL-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.
