From: Differences in the tissue tropism to chicken oviduct epithelial cells between avian coronavirus IBV strains QX and B1648 are not related to the sialic acid binding properties of their spike proteins

Figure 6

Binding of virus particles to oviduct epithelial cells. Viral particles of QX and B1648 strains, obtained by ultracentrifugation of virus containing allantoic fluids through a 25% sucrose cushion, were both able to bind to the epithelial cells of the oviduct. Binding was detected with a monoclonal antibody directed against the spike protein. Pictures were made using a 100 fold oil immersion objective.
