Common packaging cell lines
Name | Feature |
---|---|
Lenti-X 293 T | 6× more virus production than 293FT and 30× more virus than 293 cells |
Lenti-Pac 293 Ta | Produces high titers |
293LTV | 293-derived, firm attachment to plates, faster growth rate, produces high titers |
293TN | Highly transfectable, produces high titers |
Platinum Retroviral Packaging | 293 T derived, produces high titers, longer stability without drug selection, three versions: ecotropic (Plat-E), amphotropic (Plat-A), and pantropic (Plat-GP) |
293RTV | Retroviral expression and packaging cell line, faster cell growth, higher retrovirus titer, firmer attachment to plates |
Phoenix-AMPHO | Amphotropic |
Table 5 contains information on commonly used packaging cell lines mostly derived from HEK293 T to achieve higher titers or for longer term virus packing. These cell lines express viral genes (gag, pol) as episomes and therefore are more efficient than other cell lines that require co-transfection of helper constructs to package virus. Some key features related to their viral packaging efficiencies are highlighted in the table for each cell line
