title: Laser cytophotometric detection of variations in spatial distribution of concanavalin-A cell surface receptors following viral infection.
abstract: Human cells in culture (H.Ep. 2) were infected with herpes simplex virus type 2 at a multiplicity of infection (m.o.i.) of 3 for 3, 18 and 36 hr. Spatial redistribution of concanavalin (Con-A) cell surface receptor sites was detected by an indirect double-antibody (peroxidase-conjugated goat anti-rabbit to rabbit anti-Con-A) immunoenzymatic staining reaction which rendered the Con-A sites visible to light microscopy and to flow laser cytophotometry. Significant spatial redistribution of cell surface Con-A receptor sites occurred within the first 3 hr after infection with herpes simplex virus type 2. The infected cells must be in the presence of Con-A for the redistribution to occur, and significant redistribution occurs only at 37 degrees C. Fixation of infected cells prior to application of Con-A prevented this spatial redistribution of Con-A receptor sites.
