Figure 6. Observation of STD signals for the αGal disaccharide and the blood-group B trisaccharide.

(A) Reference ¹H NMR spectrum and (B) STD NMR spectrum of Galα3GalαOMe in the presence of bovine norovirus VLPs. (C) Reference ¹H NMR spectrum and (D) STD NMR spectrum of the methyl glycoside of the blood group B-trisaccharide in the presence of bovine norovirus VLPs. STD signals are only observed for Galα3GalαOMe. The blood group B-trisaccharide shows no STD effects, and is therefore not recognized by the VLPs. Spectra were recorded at 500 MHz at a temperature of 282 K with 256 and 816 scans, respectively.
