Microscopy of virus-cell fusion assay. Fluorescence microscopy of the Halorubrum sp. SS7-4 cells infected with fluorescently labelled HRPV-6 (a) or fluorescently labelled spikeless HRPV-6 particles (b). c A close-up of cells infected with HRPV-6 showing spreading of fluorescence evenly along the cell and viral particles fluorescing brightly. Pictures are representatives from at least three separate experiments all of which contained both treatments. Scale bar 5 μm (a, b) and 2 μm (c). DIC, cells imaged using differential interference contrasting; R18, cells imaged using fluorescence for rhodamine label; merge, an overlay of the two channels used.
