Common transfer vectors for lentivirus and retrovirus
Retrovirus | Use | Backbone | Selection |
Retroviral vector for shRNA expression | pMKO.1 | Puromycin, neomycin | |
Retroviral expression | pBABE | Hygromycin, puromycin | |
Mammalian retroviral gene expression with GFP | MSCV-IRES-GFP | GFP | |
Lentivirus | Lentiviral expression | pWPXL | GFP |
Lentiviral shRNA expression | pLKO.1 | Puromycin | |
Tet-inducible lentiviral shRNA expression | Tet-pLKO | Puromycin | |
cDNA expression | FUGW | Bleomycin | |

cDNA expression | pLJM1-EGFP | Puromycin |
Table 4 describes popular viral transfer vectors that are compatible with retroviral and lentiviral systems for the expression of cDNA or shRNA. Some have features for doxycycline-inducible or Cre-Lox control for conditional expression. Information on the selection marker of the plasmid is also provided
