Percentage of live HEK-293T cells expressing GFP after incubation with adenoviral vector that had undergone 1 min of exposure in suspension with disinfectants A through D diluted with FBS to 75%, 50%, or 25% of the recommended concentration. Percentages after exposure to disinfectants A and D at 75% concentration were not significantly different from those of cells unexposed to virus. Data are expressed as means without error bars, due to the degree of variability; values significantly (*, P < 0.05; †, P < 0.01) different from those of the medium controls (virus unexposed to disinfectant) are indicated.
