DBP and infection: Thus, at 24 h postinfection (p.i.), AdLacZ (multiplicity of infection [MOI], 70 PFU/cell)-, AdE4orf6/AdE1B55K (MOI, 35 PFU/cell)-, and Ad5 H5pg4100 wild-type (MOI, 1 fluorescent focus-forming unit [FFU])-infected cells were analyzed by confocal fluorescence microscopy following immunostaining with anti-DBP antibodies and treatment with 4′,6-diamidino-2-phenylindole (DAPI).
