DNA Transfection
The term transfection is commonly used to describe the process of adding DNA into cells with a view to mediating protein expression of the transgene of interest. Although DNA transfection is the most commonly adopted technique, the term can also be applied to RNA transfection, where the purpose may also be to mediate protein expression or to achieve knockdown of the transcription of a specific gene, either by RNAi, ribozyme or antisense methodologies.
