Practical application of synthetic A and B blood group immunoadsorbents. 1981

G Crawford, and A Adatia, and D H Naylor, and B P Moore

The effectiveness of synthetic blood group A and B immunoadsorbents in removing anti-A and anti-B from human sera was evaluated. The sera contained specific alloantibodies and were destined for use as diagnostic reagents. Both Synsorb-A(TM) and Synsorb-B(TM) removed all saline anti-A or anti-B activity from 20 sera tested. All trace of anti-A activity detectable by the indirect antiglobulin test was removed from only 20% of sera; anti-B with similar reactivity was removed from 66% of sera. Specific (wanted) alloantibody titres were reduced by synsorb-A in 60% of sera, but were unaffected by Synsorb-B. Despite these shortcomings, such immunoadsorbents are of value particularly when cells of appropriate phenotype are unavailable for absorptions.

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
D007518 Isoantibodies Antibodies from an individual that react with ISOANTIGENS of another individual of the same species. Alloantibodies
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. ABH Blood Group,ABO Blood Group,ABO Factors,Blood Group H Type 1 Antigen,H Blood Group,H Blood Group System,ABO Blood Group System,Blood Group, ABH,Blood Group, ABO,Blood Group, H,Blood-Group System, ABO,Factors, ABO,System, ABO Blood-Group
D000042 Absorption The physical or physiological processes by which substances, tissue, cells, etc. take up or take in other substances or energy.
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.
