Lentivirus System Resources

Lentiviruses are members of the Retroviridae family of viruses, with HIV-1 being the most widely studied. Lentiviral vectors are able to deliver genes into a broad range of mammalian cell lines and tissue types and to infect both dividing and non-dividing cells. Recombinant lentivirus systems and lentiviral transfection/transduction are powerful tools and methods for gene delivery and gene therapy. Because they can stably integrate transgenes into the host genome, lentiviruses are unique tools for generating stable cell lines for long term expression, enabling scientists to stably overexpress or silence genes, immunize against a range of diseases, generate transgenic organisms, and much more.

Our collection of resources introduces you to the basics of the lentivirus system, including the 1st, 2nd, and 3rd generation recombinant systems, how to package your own lentivirus, how to infect your cells, and much more.
