Infection of H441 cells with GFP-RSV rRA2. A, H441 cells 6
days post-infection with either GFP-RSV rRA2 (rRA2) or UV-inactivated GFP-RSV
rRA2 (UV-rRA2) at m.o.i. = 1. Cells were imaged under bright field
(BF), green (GFP), or blue filters (Nuclei, Hoechst 33258 staining)
with a 10× objective lens. Scale bars equal 200 μm.
B, infection rates (number of GFP(+)/total cell number) after rRA2
infection with m.o.i. = 1 (solid) or 5 (striped bars). Data
are the means ± 1 S.E. (n = 3 independent experiments).
