Neutralization of A549 cells with a luciferase-expressing adenovirus (Ad5-Luc2). Neutralization was determined by transgene expression inhibition in cells pretreated with mixed serum at different dilutions: 1:100, 1:500, and 1:1000. Neutralization efficiency was calculated from triplicate measurements; quadrate measurements are shown for 1.0 × 106 viral particles (VP) of Ad5-Luc2 and 5 × 104 A549 cells per well. *p < 0.05 and **p < 0.01
