Figure Lengend Snippet: ( A ) Immunoblots of lysates from HeLa cells mock-infected or infected with OROV BeAn19991 (MOI 5). Membranes were probed with HRP-conjugated nanobody-Fc fusions or with a polyclonal antibody against OROV plus anti-mouse secondary antibody, as indicated. Membranes were subsequently probed for GAPDH as a loading control. ( B ) Immunocytochemistry of HeLa cells infected with OROV BeAn19991 (MOI 0.5). Cells were probed with AlexaFluor (AF)568 conjugated OROV nanobodies against N (NpE3) or Gc Spike (SpE8), with a polyclonal antibody against OROV and with an antibody against TGN46, plus appropriate secondary antibodies. Nuclei are stained with DAPI (blue). Scale bar = 10 µm. ( C ) Nanobody-Fc fusions that recognise Gc spike neutralise OROV infection in vitro. Plaque reduction neutralisation assay using Gc spike Nb-Fc fusions, performed using OROV BeAn19991 (top) or AM0088 (bottom). Data for three independent experiments plus SD and ND 50 values are shown. .
