Figure 5. PGT128 family antibodies can utilize alternate glycan sites in the high-mannose patch to neutralize isolates when the N332 or N334 glycan sites are removed by alanine mutagenesis.
Neutralization potency of the PGT128 antibody family was measured on a panel of (A) 92RW020, (B) 92TH021 and (C) JR-CSF glycan mutant viruses for which N-linked glycan sites in the V3 region were removed alone or in combination with other N-linked glycan sites.
