Abstract:
To construct retroviral vector carrying green fluorescent protein (GFP) gene, and determine whether T cells can be infected by retrovirus, the phosphoglycerate kinase (PGK) promoter gene and GFP full-length cDNA were subcloned into the retroviral vector pLXSN. The recombinant vector was transfected into PA317 packaging cells by DNA-calcium phosphate coprecipitation. The G418 resistant clones were selected, then NIH3T3 cells and T cells were infected by the culture supernatant of the retrovirus containing GFP. The results showed that GFP expression in packaging cell line PA317 was detectable under fluorescence microscope, which demonstrated that the GFP retrovirus were able to infect T cells. It is concluded the retrovirus vectors can introduce a foreign gene into T cells efficiently and can be used as important tools to deliver gene into T cells.
