Abstract:
Objective To construct recombinant lentivirus with the gene STAT3 of the Mus musculus,measure the expres-sion of STAT3,and conduct lentivirus packing and identification.Methods The mRNA of mouse myoblast was extracted and transformed into STAT3 cDNA by the special primer.then,STAT3 cDNA was amplified and reclaimed and inseted into pLVX-IRES-ZsGreen1 vector.Cleavage map and sequencing analysis were used for identification of the recombinant lentivirus vector (pLVX-IRES-ZsGreen1-STAT3).293 T cells were transfected with main vector pLVX-IRES-ZsGreen1-STAT3.and 48 h later, Western blott detected the expression of STAT3 protein.Lentiviral vectors were packaged and the titer was determined.Results The lentiviral vector plasmid pLVX-IRES-ZsGreen1-STAT3 was identified correctly by cleavage map and Co-transfection of 293 T cells with 48 h,the expression of STAT3 was significantly enhanced by western blot.And DNA sequencing analysis confirmed that STAT3 gene sequencing was exactly the same with that reported by genbank.Conclusion Lentiviral vector carrying STAT3 was successfnlly constructed and could express STAT3 with high efficiency,and can be used in further study.
