Why use lentivirus as a gene delivery tool?  

Why use lenti as a gene delivery tool? For many cells, such as primary cells or stem cells, regular chemical-based transaction reagents fail to deliver genes into those cells. Lentivirus, however, can efficiently deliver genes into them. OriGene is a lenti leader and offers genomewidelenty products for human mice and rats. We also offer a series of lentil kits to help lentiviral production in your own lab. Two lenti product lines are available until for general expression or lenti shRNA for gene knockdown. For each lentiviral product, there are two options one lentiviral plasmid, two lentiviral particles.
