Lentiviral Expression Complete Systems

Lentiviral Expression Complete Systems

Our ViraSafe™ Lentivirus Expression Complete Systems provide a safer method even compared to other 3rd generation expression systems. Overlap with native HIV genes has been reduced much further, thereby substantially reducing the chance of generating replication-competent virus. The system has been engineered so that lentiviral titers remain at the levels of third generation systems.

Ecotropic Expression Systems assemble 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 procedures.

Pantropic Expression Systems assemble VSVG-pseudotyped lentiviruses which can easily infect virtually any cells regardless of their species of origin.

All ViraSafe™ Expression Systems contain a cloning/expression vector, a LacZ control vector, and three packaging vectors.
