Lentiviral gene transfer technologies exploit the natural efficiency of viral transduction to integrate exogenous genes into mammalian cells. This provides a simple research tool for inducing transgene expression or endogenous gene knockdown in both dividing and nondividing cells. This chapter describes an improved protocol for polyethylenimine (PEI)-mediated multi-plasmid transfection and polyethylene glycol (PEG) precipitation to generate and concentrate lentiviral vectors.
