The carbohydrate structures determining the ABO blood group system have been almost completely characterized. Recent advances in the stereoselective synthesis of such complex structures have made it possible to prepare pure oligosaccharides in large quantities and to study their possible uses for diagnostics and pharmaceutical processing techniques. In the experiments described here A and B blood group specific determinants were synthesized and bound to solid phases by means of suitable spacers in order to study their use as immunoadsorbents. The objective was to adsorb blood group specific antibodies from positive sera and from immunoglobulin preparations. It was shown that the anti-A and anti-B antibodies bound to the immunoadsorbents with high affinity could be removed effectively. The effects were achieved both using affinity chromatography and "batch processing".

UI MeSH Term Description Entries
D007164 Immunosorbents An insoluble support for an ANTIGEN or ANTIBODIES that is used in AFFINITY CHROMATOGRAPHY to adsorb the homologous antibody or antigen from a mixture. Many different substances are used, among them SEPHAROSE; GLUTARALDEHYDE; copolymers of ANHYDRIDES; polyacrylamides, etc. Immunoadsorbent,Immunoadsorbents,Immunosorbent
D002621 Chemistry A basic science concerned with the composition, structure, and properties of matter; and the reactions that occur between substances and the associated energy exchange.
D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000017 ABO Blood-Group System The major human blood type system which depends on the presence or absence of two antigens A and B. Type O occurs when neither A nor B is present and AB when both are present. A and B are genetic factors that determine the presence of enzymes for the synthesis of certain glycoproteins mainly in the red cell membrane.

D000918 Antibody Specificity The property of antibodies which enables them to react with some ANTIGENIC DETERMINANTS and not with others. Specificity is dependent on chemical composition, physical forces, and molecular structure at the binding site. Antibody Specificities,Specificities, Antibody,Specificity, Antibody
D000936 Antigen-Antibody Complex The complex formed by the binding of antigen and antibody molecules. The deposition of large antigen-antibody complexes leading to tissue damage causes IMMUNE COMPLEX DISEASES.
