title: Isolectins from soybean (Glycine max).
abstract: The major lectin in seeds of a soybean cultivar (Glycine max cv D68-127) has been purified to apparent homogeneity by hydroxyapatite and DEAE-cellulose chromatography. In the latter, the behavior of the lectin was similar to that of the minor isolectins previously described in other soybean cultivars. Molecular weights of 92 000 for the molecule and 23 000 for the subunits were determined by gel filtration and sodium dodecyl sulfate-gel electrophoresis; these are smaller than those previously reported for the major lectin in another soybean variety. Hemagglutination by the lectin was inhibited specifically by N-acetyl-D-galactosamine and galactose-containing sugars.
