Figure 1From: Kinetics of antibody-induced modulation of respiratory syncytial virus antigens in a human epithelial cell lineIndirect immunofluorescence of RSV antigen in infected epithelial cells. Viral proteins in HEp-2 cells, which had been infected at m.o.i. of 50 for 12 h permeabilized and fixed with acetone and cold methanol, were visualized by indirect immunofluorescence with an epifluorescent microscope. First antibody: goat anti-RSV; second antibody: rabbit anti-goat. A) RSV-infected cells; B) mock-infected cells.Back to article page
