Stable Expression by Lentiviral Transduction of Cells

Lentiviral gene transfer represents a versatile and powerful method for genetic transduction of many cell lines and primary cells including “hard-to-transfect” cells. As a consequence of the integration of the recombinant lentiviral vector into the cellular genome, the transgene is stably maintained, and long-term producing cells are established. Here, we describe the current state of the art and give details for lab-scale production of lentiviral vectors as well as for infection and titration of the viral vectors.
