Examination of CHLA and PUG treatment on HCMV cell-to-cell spread. HEL cell monolayers were inoculated and infected with HCMV for 2 h, washed with PBS to remove excess surface bound virus, and covered with an overlay medium to prevent secondary infection. Initial virus plaques were allowed to form in the subsequent infections and CHLA, PUG, Heparin, DMSO control were added to the overlay medium for an additional incubation time before analysis of viral plaque size by immune fluorescence microscopy at 5 days post-infection as described in Methods. Representative virus plaques/foci are shown after three independent experiments were performed. Scale bar indicates 100 μm.
