Fig. 2From: Comparative neutralizing potencies of antibodies suggest conservation as well as mechanistic differences in human cytomegalovirus entry into epithelial and endothelial cellsNeutralization 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)Back to article page
