  • Title: The lectin binding sites on the plasma membrane components of human lymphoblastoid cell lines.
    Author: Gürtler LG, Sramota B, Cleve H.
    Journal: Hoppe Seylers Z Physiol Chem; 1979 Dec; 360(12):1819-28. PubMed ID: 316801.
    Abstract:
    The plasma membrane components of five human B-cell lines and three human T-cell lines were separated by dodecyl sulfate polyacrylamide gel electrophoresis, incubated with the radioactive labeled lectins from lentil, castor bean, wheat germ, Phaseolus bean, peanut, gorse and the Roman snail and the molecular weights of the binding sites determined. The lentil, castor bean and wheat germ lectin bound to multiple components from molecular weights (Mr) 20 000 to 200 000 within the plasma membranes, whereas peanut lectin bound preferentially to glycoproteins of Mr 150 000 and 83 000 in B-cells, and 150 000 and 130 000 in T-cells. The gorse lectin bound to a 220 000 component in B-cells which was not labeled in T-cells.
