Fig. 6From: Antibodies against Lewis antigens inhibit the binding of human norovirus GII.4 virus-like particles to saliva but not to intestinal Caco-2 cellsBlockade of binding of NoV VLPs to D-Caco-2 cells by anti-NoV mAbs. a (a) D-Caco-2 cells were incubated with GII.4-2004 variant (v2) VLPs. (b) Same concentration of VLPs was pre-incubated with the homologous variant-specific mAb (at 1:100 dilution of the antibody) and added to D-Caco-2 cells; (c) negative control incubated with PBS. b Measurement using the ImageJ software program of the fluorescence intensity revealing NoV VLPs (v2) bound to D-Caco-2 cells and its blockade by anti-v2.mAbBack to article page
