Fig. 1From: 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 human sera. Neutralizing activities of sera from eight normal CMV-positive human donors were determined using ARPE-19 epithelial cells or HAEC endothelial cells infected with the GFP-tagged CMV strain UxcAp66. GFP values measured seven days post infection were normalized to percent maximum (upper asymptote) and IC50 values were determined as the inflection points of four-parameter curves fitted to plots of GFP activity in triplicate wells vs. Log (serum dilution)Back to article page
