Transfection is the process of deliberately introducing nucleic acids into cells. The term is used notably for non-viral methods in eukaryotic cells. It may also refer to other methods and cell types, although other terms are preferred: "transformation" is more often used to describe non-viral DNA transfer in bacteria, non-animal eukaryotic cells and plant cells.
Genetic material (such as supercoiled plasmid
DNA or siRNA constructs), or even proteins such as antibodies, may be transfected.
