Avian influenza virus strains representing most hemagglutinin (HA) subtypes were compared with human influenza A (H1N1, H3N2) and B virus isolates, including those with no history of passaging in embryonated hen's eggs, for their ability to bind freeN-acetylneuraminic acid (Neu5Ac) and sialyloligosaccharides in a competitive binding assay and to attach to gangliosides in a solid-phase adsorption assay...
Synthetic sialylglycoconjugates bearing 3′-sialyllactose, 6′-sialyllactose, or 6′-sialyl(N-acetyllactosamine) moieties attached to the polyacrylic acid carrier (P-3-SL, P-6-SL, and P-6-SLN, respectively) were prepared and tested for their ability to bind to influenza virus isolates from different hosts in a competitive solid phase assay. The virus panel included egg-grown avian and porcine strains,...
Sialic acids are essential components of cell-surface receptors utilized by influenza viruses. To evaluate the recognition of asialic sugar parts of the receptor, three representative strains of human influenza A and B viruses were tested for their binding of a panel of sialyloligosaccharides. The highest affinity binding carbohydrate determinants recognized by the viruses in a context of different...
