Oligosaccharides and Discordant Xenotransplantation
Immunological Reviews, 1994The initiating factor in the hyperacute rejection of pig organs by human or non-human primates is believed to be related to the presence of preformed "natural" antibodies in the host. In 1991, we demonstrated that human anti-pig antibodies were IgG, IgM and IgA and bound most strongly to oligosaccharides with an alpha galactose (alpha Gal) terminal ...

Mucopolysaccharides and Oligosaccharides
1995Mucopolysaccharides and oligosaccharides are essential constituents of the organism. They occur in connective tissue, parenchymal organs, cartilage and the nervous system. Mucopolysaccharides (for which the preferred term is glycosaminoglycans) are complex heterosaccharides consisting of long sugar chains rich in sulphate groups.

Synthesis of nigero-oligosaccharides
Carbohydrate Research, 1992Nigerose [alpha-D-Glcp-(1----3)-D-Glcp], nigerotriose, nigerotetraose, and nigeropentaose have been synthesized by chain elongation starting at the reducing end, from the corresponding octa-, undeca-, tetradeca-, and heptadeca-beta-D-acetates, respectively, via thioglycoside-mediated 1,2-cis coupling, using 1,2,4,6-tetra-O-acetyl-beta-D-glucopyranose ...

Oligosaccharides of Human Milk
Nature, 1957THE presence of fucose as a constituent sugar in oligosaccharides obtained from human milk was reported by Kuhn1 in 1952. Since that time Kuhn and his associates have characterized four oligosaccharides from this source, in all of which fucose is found: a trisaccharide, fucosido-lactose; two pentasaccharides referred to as lacto-N-fucopentaoses I and ...

Oligosaccharide chains of glycoproteins
1990Glycoproteins are widely distributed in nature, not only in animal cells but also in plants, microorganisms and viruses. Structurally, glycoproteins can be distinguished from other proteins by the presence of sugars covalently linked to the polypeptide backbone.

The Raffinose Family of Oligosaccharides
1954Publisher Summary This chapter discusses raffinose and those saccharides which are related to raffinose by virtue of having one or more α-D-galactopyranosyl groups in their structures. These D-galactosyl groups are found in nature joined to sugars, such as D-glucose, to sucrose, to certain polysaccharides, and to a few non-sugars, such as glycerol ...

It is very difficult to detect a faint amount of oligosaccharide, because generally they have only hydroxyl and aldehyde groups. Thus, many studies have been reported on high-sensitive detection of oligosaccharides by radio-labeling or tagging of a UV-absorbent.
