Construction and identification of recombinant baculovirus of the novel CEA vaccine / 第三军医大学学报

ABSTRACT

Objective To design a novel efficient CEA vaccine of fission epitopes with the vehicle of HPV16L1,and construct the recombinant baculovirus in Bac-to-Bac baculovirus expression system.Methods The recombinant baculovirus expression vector pFastBac1-V was constructed.HPV16L1 and CEA-PADRE synthesis primers were inserted into bacmid in E.coli DH10Bac with the help of Tn7 transposition system.Then the recombinant baculovirus was got by infecting insect cell sf9.Results HPV16L1 and CEA-PADRE synthesis primers that were cloned to the baculovirus transfer vector pFastBac1 were assessed by restriction analysis and direct sequencing.The recombinant baculovirus of the novel vaccine had been constructed.After infected sf9,the correct fragment was amplified by PCR.Conclusion The baculovirus of CEA vaccine of fussion epitopes with the vehicle of HPV16L1 was constructed.
