  • Title: Isolation and characterization of a new hemagglutinin from the red alga Gracilaria bursa-pastoris.
    Author: Okamoto R, Hori K, Miyazawa K, Ito K.
    Journal: Experientia; 1990 Sep 15; 46(9):975-7. PubMed ID: 2209806.
    Abstract:
    A new agglutinin has been isolated from the red alga Gracilaria bursa-pastoris by affinity chromatography on a yeast mannan-Cellulofine column. This agglutinin was isolated as a monomeric glycoprotein with a relatively low molecular weight. It had an isoelectric point of 4.7 and contained large amounts of Gly, Asx and Glx. It agglutinated trypsin-treated rabbit erythrocytes at the low concentration of 30 ng/ml. The activity was inhibited only by glycoproteins bearing N-glycans. This agglutinin also showed mitogenic activity for mouse splenic lymphocytes.
