The invention relates to a glycopolypeptide that includes one or more modified amino acid residues having a sidechain comprising a monosaccharide or an oligosaccharide, wherein the glycopolypeptide binds specifically to a carbohydrate-binding monoclonal antibody with an affinity of less than 100 nM. Immunogenic conjugates that include the glycopolypeptide, and pharmaceutical compositions that include the glycopolypeptide or the immunogenic conjugate are also disclosed. Various method of using the glycopolypeptides, immunogenic conjugates, and pharmaceutical compositions are disclosed, including inducing an immune response, inhibiting viral or bacterial infection, treating a cancerous condition, and detecting a neutralizing antibody.
