Figure 1.
RV’s cellular receptor JAM-A is present on the BV envelope. (a) Western blot analysis of Sf9 cells infected with BVJAM. The blot was reacted with mAb α-HA followed by antibody-alkaline phosphatase, to detect the presence of JAM-A in infected cells. (b–d) Electron microscopic images of BVJAM, negatively stained using uranyl acetate and incubated with mouse mAb α-JAM-A (i = sc-53623, ii = ab17261) followed by α-mouse antibody tagged with 10-nm colloidal gold. (b) Example of a BVJAM field on grid showing low background labelling. (c,d) Enlargements of BVJAM virions bearing respectively a single (c) or multiple (d) gold grains.
