METHOD FOR DETERMINATION OF RECOGNITION SPECIFICITY OF VIRUS FOR RECEPTOR SUGAR CHAIN

摘要

A method in which the recognition specificity of a virus for a receptor sugar chain can be easily determined with a simple instrument or apparatus is provided. In a method for determining the recognition specificity of a virus for a receptor sugar chain or for determining the change in a host infected in accordance with the mutation of virus comprising, a sample of the virus is brought into contact with a support having a polymer with sialo-oligosaccharide immobilized on the surface thereof; and the degree of binding therein is assayed to determine the recognition specificity of said virus for said receptor sugar chain and to determine the change in a host range. The method is suitable for the surveillance of virus.
