Synthetic HBGAs and KDs for binding to GII.4 Saga and GII.4 MI001 P-dimers [44,45]. The abbreviations (N,N), etc. refer to the deamidation status of Asn373. (N,N) stands for not deamidated, and (iD,iD) stands for fully deamidated, i.e. both Asn373 residues have been transformed into isoAsp residues.
