Figure 3From: Resolving the titer of murine cytomegalovirus by plaque assay using the M2-10B4 cell line and a low viscosity overlayLow viscosity CMC is not sufficient to prevent viral spread on M2-10B4 monolayers. Monolayers begun with 1.25 × 105 M2-10B4 cells (subconfluent) were infected and overlaid with low viscosity CMC (158 mPas final, left images) or intermediate viscosity CMC (480 mPas final, right images). Monolayers were fixed and stained 5 days after infection with BAC-derived MCMV. Sizing bars = 1 mm.Back to article page
