Cloning of the sFLT01, vector transfection and western blot analysis. a The polyhistidine-tag was added at the end of sFLT01 sequence, and cloned into pAAV-MCS-GFP plasmid. SFLT01-HisTag fragment digestion examined with the EcoRI and BamHI enzymes, resulted in 1116 bp fragment (sFLT01-HisTag) indicating that the target sequence was inserted in the vector body. b Transfection of DU145 cells with the recombinant pAAV-sFLT01-HisTag-GFP plasmid showed more than 90% of the cells were positive for GFP, (a): DU145 cells; no transfection, (b): GFP over expression in DU145 cells which had been transfected by pAAV-sFLT01-His Tag-GFP. c CM of HEK293T cells that had been transfected by pAAV-sFLT01-HisTag-GFP was collected 72 h post transfection, purified with nickel affinity chromatography column and applied in western blot experiment by the human VEGFR1/Flt-1 primary antibody
