ViraSafe™ Lentiviral Packaging System, Ecotropic (VPK-205)

Our ViraSafe™ Lentiviral Packaging Systems contain three packaging plasmids for co-transfection with your own third generation lentiviral expression construct. If you need an expression vector as well as the packaging plasmids, consider our ViraSafe™ Lentiviral Expression Complete Systems. Our Ecotropic Packaging System assembles lentiviruses with an ecotropic envelope protein which will readily infect only mouse and rat cells via receptor-mediated binding, providing an additional level of safety. However, ecotropic viruses are not as stable upon freezing and will not survive ultracentrifugation procedure
