Product Details

Lentivirus based on HIV-1 provides a powerful means for gene expression because it can infect both dividing and non-dividing cells. Other 3rd generation lentiviral packaging systems provide a reduced risk of replication-competent virus, but a small risk remains.

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.

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