Variations of the 1H chemical shifts of the C-IFNγ on complex formation with the three oligosaccharides: dp8 (open bars), dp4 (grey bars) and dp2 (closed bars). Final molar ratios were of 1:2 C-IFNγ/oligosaccharide. The difference in the chemical shifts observed in the TOCSY spectra is displayed as a function of the sequence number.
