(a) Analysis of E3/49K secretion from HAdV-D28-infected cells. Molecular sizes are indicated in kDa. Full immunoblot is shown in Supplementary Fig. 8a. (b) Detection of the E3/49K protein expressed at the surface of HAdV-D28-infected cells by immunofluorescence (left panel) and flow cytometry (right histograms). Grey-filled histograms represent staining corresponding to non-infected cells, black histograms show E3/49K surface expression on HAdV-D28-infected cells at the indicated hours post infection (p.i.). Scale bar, 10 μm. (c) Binding of CD45, LILRB1 and PUNC purified ECDs, found to interact with HAdV-D28 E3/49K, to infected cells. Grey-filled histograms represent binding of a control recombinant protein, whereas black histograms show binding of the indicated E3/49K hits to the surface of infected cells. Assays shown are representative of two independent experiments.
