Figure 2. Titers of GP pseudotyped retroviral vectors on various cell lines.
Titers were measured on (A) human kidney endothelial cells (293A, human T lymphocytes (CEM) and murine T lymphocytes (TIB27), and (B) rodent cell lines. Values shown are mean +/− SE for 2-8 independent experiments. All vector/cell combinations that gave no titer (*) were confirmed using 10 X concentrated stocks of vectors.
