FIG. 4.
Rate-zonal centrifugation of HSV-1 capsids isolated from the nuclear fraction and analyzed for the presence of tegument proteins VP22 and UL11. At 15 h after infection the capsids from the nuclear fraction were obtained, separated by rate-zonal centrifugation as described in the legend to Fig. 2. The same blot was probed sequentially using antibodies specific for the major capsid protein VP5 and tegument proteins VP22, UL11, and UL37 (positive control).
