    Journal: J Biochem; 1990 Nov; 108(5):766-77. PubMed ID: 2081734.
    Abstract:
    Total non-acid glycosphingolipids were isolated from the kidneys of single pigs serologically typed on their red blood cells as blood groups O and A. Glycolipid species were purified by HPLC and structurally characterized by thin-layer chromatography, mass spectrometry, proton NMR spectroscopy, degradation analysis, and reactivity with various monoclonal antibodies, Gal alpha 1-4Gal-specific E. coli bacteria, and lectins. Glucosyl-, globotriaosyl-, and globotetraosylceramides were the predominant molecular species with lactosyl- and globopentaosylceramides (IV3GalGb4Cer) as abundant constituents too. Small amounts of galactosyl- and digalactosylceramides were also present. In the blood group O pig kidneys, blood group H antigens based on four different core saccharides (types 1, 2, 4, and lactosyl core) were identified and the major blood group structure was V2FucIV3Gal-Gb4Cer. In the kidneys from the blood group A pig the corresponding blood group A antigens were found and in addition, a type 3 chain blood group A antigen was indicated by mass spectrometry and by its reactivity with a monoclonal antibody. Trace amounts of the type 2 chain-based X and Y antigens were found while blood group B antigens and the type 1 chain based Lewis antigens could not be detected. The ceramide part of the glycolipids was mainly composed of dihydroxy 18:0 long chain bases and non-hydroxy 16:0-24:0 fatty cids.
