Principal and experimental results of the synergistic interactions between the DBA beads and several sugars from one glycopeptide. a The structure of a dendrimer conjugated with BA derivative II (benzoboroxole). b An example of the synergistic interactions between multiple benzoboroxole molecules in a dendrimer and several sugars within one glycan of a glycopeptide. c The effect of synthesis cycles and the corresponding dendrimer size on the enrichment of glycopeptides: total glycopeptides (blue), unique glycopeptides (dark blue), and glycoproteins (green) identified in parallel experiments. d The effect of reaction time on the N-glycopeptide identification
