Flow cytometric analysis of EGFP expression in NIH 3T3 (A) and Rat2 (B) cells transduced with aMFG-EGFP retroviral-containing supernatant. The corresponding profiles for cells mock-transduced with GP+envAm12-derived supernatant (thin lines) are overlaid for comparison. Percentages of cells positive for EGFP expression are indicated.
