Immunochemical 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 کاملAn aerobic soil microorganism which decomposes blood group substances. I. Metabolic and immunochemical studies.
A number of microorganisms have the ability to degrade cellulose, agar, bacterial polysaccharides, and blood group substances. The Myxococcus of Morgan and Thaysen (1933) was shown to split blood group A substance in horse saliva but not the A substance in peptone (Landsteiner and Chase, 1935a, b). It also attacked the specific polysaccharide of Shigella dysenteriae (Shiga and Flexner), pneumoc...

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
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 کاملBlood group substances as
The level of cellular differentiation of human oral, sulcular, and junctional epithelium was compared by immunohistochemical analysis of cell membrane-associated blood group-specific carbohydrates. Identification of the blood group A-specific carbohydrate and its two immediate precursor substances, type 2 chain H and N-acetyllactosamine. was accomplished by an indirect immunofluorescence techni...
