Generation of Stable Expression Mammalian Cell Lines Using Lentivirus.

ABSTRACT

Lentiviruses are used very widely to generate stable expression mammalian cell lines. They are used for both gene down-regulation (by using shRNA) or for gene up-regulation (by using ORF of gene of interest). The technique of generating stable cell lines using 3rd generation lentivirus is very robust and it typically takes about 1-2 weeks to get stable expression for most mammalian cell lines. The advantage of using the 3rd generation lentivirus are that are very safe and they are replication incompetent.
