Thermo Scientific TurboFect Transfection Reagent is recommended for efficient transfection of plasmid DNA. Distinct from lipid-based formulas, TurboFect is a sterile solution of a proprietary cationic polymer in water. The polymer forms positively-charged complexes with DNA that are both compact and stable. These complexes protect DNA from degradation and facilitate efficient plasmid delivery into eukaryotic cells.
