The optimal transfection conditions for efficient transgene delivery into a specific cell type should be empirically determined, particularly in cases involving unusual cell types. We compared the conditions for effective introduction of transgenes into Siberian sturgeon (Acipenser baerii) cell lines by evaluating the cytotoxicity and transfection efficiency of three commercially available transfection reagents: Lipofectamine 2000, X-tremeGENE HP DNA Transfection Reagent, and GeneJuice Transfection Reagent. Plasmid vectors containing the gene encoding enhanced green fluorescent protein were mixed with each of the transfection reagents using reagent-to-plasmid ratios of 1:1, 2:1, and 4:1. Then, the complexes were used to transfect three Siberian sturgeon cell lines derived from the heart, head kidney, and gonad. Cytotoxicity and transfection efficiency were measured via flow cytometry after propidium iodide staining. No significant cytotoxicity was observed at the optimal treatment conditions in all cases, with the exception of Lipofectamine 2000-treated gonad-derived cells. Although the transfection efficiencies in A. baerii cells were generally low, X-tremeGENE HP DNA Transfection Reagent showed the highest transfection efficiency at ratios of 2:1 or 4:1, depending on the cell type. Hence, X-tremeGENE HP DNA Transfection Reagent can be used to effectively transfer foreign genes into three A. baerii cell lines.
