FIG. 2.

Immunofluorescence analysis of HFFF-2 cells nonproductively infected with dl1403 at low multiplicity at 24 h after infection. The fluorescence intensity of isolated cells stained for ICP4 and ICP27 or for ICP4 and ICP8 was compared with that of cells in the small number of plaques on the coverslip. The images in the six upper panels were captured under identical scanning conditions and have been printed without alteration of brightness or contrast. The same is true for the six lower panels. Further details on the relative amounts of ICP27 and ICP8 expressed in nonproductively infected cells are given in the text.
