Synthetic multivalent V3 glycopeptides display enhanced recognition by glycan-dependent HIV-1 broadly neutralizing antibodies.


ABSTRACT: We describe here the synthesis of novel multivalent HIV V3 domain glycopeptides and their binding to broadly neutralizing antibodies PGT128 and 10-1074. Our binding data reveal a distinct mode of antigen recognition by the two antibodies and further suggest that multivalent glycopeptides could mimic the neutralizing epitopes more efficiently than the monomeric glycopeptide.
