A library of 15 N-linked oligosaccharide structures was prepared from ovalbumin and characterized using high-field NMR and mass spectrometry. The oligosaccharides were enzymatically released from ovalbumin glycopeptides, and the reducing ends were reacted with ammonium bicarbonate to form oligosaccharide-glycosylamines. These
A novel approach to 14C label N-linked oligosaccharides.
L-para-Tyrosine was linked to ortho-hydroxyaniline, meta-hydroxyaniline and para-hydroxyaniline giving three distinct tyrosinamide molecules. The new extended amino acid derivatives were constructed to imitate, in part, the estradiol (E(2), the natural female sex hormone) nucleus. The resulting tyrosinamides were then linked

N-linked oligosaccharides from glycoproteins can be either analyzed on a sub-nanomole scale or preparatively purified on a multi-micromole scale. Each goal necessitates a unique analytical strategy often involving oligosaccharide derivatization to enhance separation and detection. Tyrosinamide-oligosaccharides were developed to facilitate
In a previous report (Tamura, T., Wadhwa, M.S., and Rice, K.G. (1994) Anal. Biochem. 216, 335-344) we described the derivatization of N-linked oligosaccharides with Boc-tyrosine resulting in the formation of tyrosinamide-oligosaccharides. Attachment of Boc-tyrosine to the reducing-end of an oligosaccharide
