Immunochemical Studies on Blood Groups
1. With purified blood group A and B specific substances from the gastric mucin of pigs precipitin reactions can be obtained in sera containing homologous isoagglutinins. By microquantitative precipitin technics the anti-A and anti-B content of normal and immune isoagglutinin-containing sera can be estimated on a weight basis. 2. There was a general correlation between antibody N precipitable f...
متن کاملImmunochemical Studies on Blood Groups
The finding that purified blood group A and B substances specifically precipitate the corresponding isoantibodies from the serum of normal and immunized individuals and that the amounts of these antibodies could be estimated by the microquantitative precipitin method (1) introduced by Heidelberger and MacPherson (2) has made it possible to apply the technics of quantitative immunochemistry to t...
متن کاملImmunochemical Studies on Blood Groups Xi. Species Differences among Blood Group a Substances*
The presence of blood group substances in any secretion or tissue is generally established by the capacity of the secretion or of extracts of the tissue to inhibit hemagglutination of erythrocytes of a given blood group by its corresponding isoantibody (cf. references 1, 2). By this technic human secretions and tissues of persons of blood group A (1, 2), the stomach linings of some individuals ...

متن کاملImmunochemical studies on blood groups LXII. Fractionation of hog and human A, H, and AH blood group active substance on insoluble immunoadsorbents of Dolichos and Lotus lectins
The purified lectins from Lotus tetragonolobus and Dolichos biflorus were coupled to Sepharose 2B to make insoluble adsorbents for purification and fractionation of blood group A and H active glycoproteins. With both adsorbents, hog gastric mucin A + H blood substance (HGM), purified by phenol-ethanol precipitation, yielded fractions showing only A, only H, or AH activities. The AH fraction was...
