- a) MC3T3-E1 cells transduced with empty vector (LXSN), LPiT1SN, or LPiT2SN retroviral vectors were challenged with retroviral vectors pseudotyped with A-MLV or GALV surface proteins and carrying a β-galactosidase encoding transfer vector.
- b) The titers on D17 cells of the vector stocks used were 1.7 × 105 CFU/mL (A-MLV pseudotype) and 1.9 × 105 CFU/mL (GALV pseudotype).
- c) Numbers indicate blue CFU per mL vector containing supernatant.
- d) No blue cells were detected in the wells.
