Transfection of cells can be accomplished by various methods, including chemical, biological, and instrument-based. This section provides an overview of the different instrument-based transfection methods available, discusses how they work, and describes their pros and cons.

Transfection can be accomplished using chemical, biological, or physical methods. Common methods include electroporation, the use of virus vectors, lipofection, and biolistics. Many types of genetic material, including plasmid DNA, siRNA, proteins, dyes, and antibodies may be transfected using any of these methods. However, no single method can be applied to all types of cells; transfection efficiencies and cytotoxicity may vary dramatically and depend on the method, cell type being utilized, and types of experiments being performed. Therefore, to obtain high efficiencies, all relevant factors should be considered in planning and selecting the appropriate transfection method.
