Lentivirus services

Delivery of genes by lentiviral vectors has been well established and is currently widely used due to several advantages: Lentiviral vectors can accommodate long sequences; the vectors seem to be non-immunogenic due to the lack of viral coding sequences transfer; the vectors are able to transduce non-dividing cells; and the products can be stably expressed due to integration into the cell chromosome.
