| 摘要 |
<p>The invention features a cell line harboring a first expression construct encoding functional Friend Murine Leukemia Virus gag/pol. In a preferred embodiment the cell line harbors a second expression construct encoding a functional viral envelope protein. In more preferred embodiments the viral envelope protein is a retroviral envelope protein; the viral envelope protein is a non-retroviral envelope protein; the cells of the cell line are stably transfected with the second expression construct; the cells of the cell line are transiently transfected with the second expression construct; and the cells of the cell line are stably transfected with the first expression construct and said second expression construct.</p> |
