FIG. 6.

Identification of S/L proteins in extracts of infected cells. Whole-cell extracts of uninfected HELF (M) or HELF infected with the VZV strains noted above the lanes were subjected to Western blot analysis using an anti-S/L rabbit serum diluted 1:500, followed by goat anti-rabbit antibody conjugated to horseradish peroxidase. The molecular masses of prestained size markers (Amersham Pharmacia Biotech, Piscataway, N.J.) are indicated at the left. The 20.1-kDa marker was too faint to see in this reproduction.
