Poly- and oligosaccharides used

Characteristics of the poly- and oligosaccharides used as antigens are listed in Table I. 

The main approaches used for identification of natural isomers of 5,7-diamino-3,5,7,9-tetradeoxynon-2-ulosonic acids and determination of structures of bacterial poly- and oligosaccharides-containing derivatives of these sugars were H and 13C NMR spectroscopy. This could be applied to both intact natural glycopolymers and carbohydrate portions obtained after delipidation of LPS as well as to oligosaccharide fragments and... 

Ized such as carbohydrates, nucleic acids, lipids, and proteins may prove available by enzymic synthetic methods. Enzymology will be useful in modifications of poly- and oligosaccharides and proteins. Enzymes will also see growth in applications in medical diagnostics and treat-... 

Primary metabolites Primary metabolites are compounds vital to tbe growth, development and function of the organism (i.e. its structure, its metaboUsm and/or its cell regulation) examples are proteins, peptides, poly- and oligosaccharides, nucleic and deoxynucleic acids and lipids. Labeled with isotopes through biotransformation processes, they can be broken down by subsequent chemical or enzymatic processes to furnish their labeled monomeric components (i.e. a-amino acids, carboxylic acids, nucleotides, sugars etc.)for a wide variety of uses. 

Immobilization of A and B blood group oligosaccharide haptens and preparation of immunoadsorbents with specificity to anti-A and anti-B antibodies has been carried out with the use of poly acrylate-coated PG (WPG-PA) [124]. Prespacered A and B-trisaccharide-fl-aminopropylglycosides were used for the synthesis. WPG-PA (1 g) quantitatively binds both haptens (2 pinole) whereas some other activated affinity supports (for example, CNBr-Sepharose 4B) do not. On the other hand, glycidoxypropyl-silica binds prespacered haptens completely but these materials reveal no specific adsorptivity.
