Cells were incubated separately with viruses encoding either reporter 1 or reporter 2; the percentages of reporter-positive cells measured by flow cytometry and the reporter 2/reporter 1 ratio are indicated ± standard deviation (SD).
Cells were incubated with both viruses, and the percentages of double-positive cells are indicated ± SD.
Theoretical percentages of reporter-positive cells upon separate incubation were calculated from double-positive cells as described in Materials and Methods.
Cells were incubated with reporter 1 and/or 24 h later with reporter 2.
