Preparation and Detection of Glycan-Binding Activity of Influenza Virus.

ABSTRACT

We describe a method to detect influenza virus using an evanescent-field-activated fluorescence scanner type glycan array and ELISA system. Neoglycoprotein was prepared by combination of organic chemistry and biomaterial preparation. These ligands were spotted on a glass plate or plastic well to make a glycan array and ELISA plate. We detected cultured influenza virus using glycan array and ELISA. Then, we showed that the neoglycoprotein binds to Cy3-labeled hemagglutinins (H1 and H5), a NeuAcα2,6LacNAc or NeuAcα2,3LacNAc recognized protein, as detected.
