COS-1 cells as packaging host for production of lentiviruses.

Abstract
We present a protocol for in vitro production of recombinant lentiviruses using COS-1 African green monkey kidney epithelial cells and HEK293T human embryonic kidney epithelial cells as packaging cells. COS-1 and HEK293T express SV40 large T antigen, amplifying transfected circular plasmids harboring SV40 replication origin. Support protocols for evaluation of transfection efficiency by in situ β-galactosidase enzyme activity assay and titer of infection-capable virions are also provided. Advantages of using COS-1 packaging cells over the standard HEK293T cells for contamination-sensitive applications or automated processing are discussed.
