Neutralization of CMV entry into epithelial and endothelial cells by HIG and epitope-specific antibodies. (A) Neutralizing activities of antibodies were determined using ARPE-19 epithelial cells (epi) or HAEC endothelial cells (endo) infected with the GFP-tagged CMV strain UxcAp66. Wells were photographed with an inverted UV microscope four (ARPE-19) or six (HAEC) days after infection. Sample dilutions are indicated on the left; ∅, virus incubated with media (no antibody)
