Gene delivery to eukaryotic cells is the technique to study the regulation of gene expression. Human astrocytoma cell line 1321N1 could be useful to study G-protein-coupled receptors (GPCRs). Different transient transfection methods, namely calcium phosphate, Lipofectamine, FuGENE, Arrest-In, and microporation (Microporator), were investigated. Results were analyzed by fluorescence-activated cell sorting and fluorescence microscope using green fluorescent protein (GFP) as a reporter gene. To verify the transfection efficiency of these techniques, the expression of human GPR17 gene (hgpr17) was analyzed by transcription quantitative polymerase chain reaction. Microporation resulted in the best method to promote enriched hgpr17 delivery into the human astrocytoma cell line.
