ViraSafe? Lentiviral Packaging System, Ecotropic

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
