ABSTRACT
Objective To construct a recombinant adenovirus vector containing the gene of major histocompatibility complex(MHC)class Ⅱ transactivator(C Ⅱ TA).Methods The restriction fragment of CIITA was inserted into pUC57 vector with EeoR Ⅰ and Xho Ⅰ.Then,recombinant plasmid pShutde-GFP-CMV CⅡTA was constructed with EcoR Ⅰ and Sal Ⅰ,and was confirmed by restriction enzyme digestion and sequeneing.After the treatment with Ⅰ-Ceu Ⅰ and Ⅰ-See Ⅰ,the fragment C Ⅱ TA from recombinant plasmid DShuttle-GFP-CMV.CⅡTA Was inserted into vector pAdxsi.And the pAdxsi-GFP-C Ⅱ TA wag packed into liposome,and was transfected to 293 cens.Results Recombinant plasmid pShuttle-GFP-CMV-C Ⅱ TA Was constructed successfully. After packed into vector pAdxsi, and transfected to 293 cells, significant virus Dlaques were observed,which showed the successful homologous recombination.The titer of the purified AdC Ⅱ TA was 2.0×10~(11) PFU/ml.Conclusions Recombinant adenovirus AdC Ⅱ TA containing gene of MHC class Ⅱ transactivator was established successfully.
