FIG. 7.

Immunohistochemical detection of VZV proteins in HELF. Cells were infected with VZV strains Ellen and Oka-SK and the recombinant viruses Oka-Δ4-3 and Oka-R. Immunohistochemical analysis of mock-infected cells is also shown. The products of ORF S/L and gC were detected using anti-ORF S/L or anti-gC antibodies. The signal was visualized after addition of AP-conjugated goat anti-rabbit immunoglobulin secondary antibody and developed with AP substrate in the presence of levamisole. The viruses infecting the monolayers are noted at the left; VZV proteins that were analyzed are identified at the top.
