MULTIMERS FOR VIRAL STRAIN EVOLUTION

摘要

The invention relates to multimers such as multimers comprising 4 copies of a binding site or peptide; tetramers of polypeptides; and tetramers, octamers, dodecamers and hexadecamers of epitopes or effector domains, such as antigen binding sites (eg, antibody or TCR binding sites that specifically bind to antigen or pMHC, or variable domains thereof) or peptides such as incretin, insulin or hormone peptides. The invention also relates to methods and uses to expand antigen specificity of binding sites, as well as vaccines, methods of vaccination and assay methods and reagents.
