Figure 3. HSV-1 entry into HCE cells is a pH dependent process. Monolayers of HCE cells were either mock treated (no treatment) or treated
with indicated concentrations of bafilomycin (A) or chloroquine (B) and exposed to HSV-1(KOS)gL86. Viral entry was measured using a spectrophotometer at an OD of 410 nm and plotted as the
mean of three samples (±SD).
