CHARACTERIZATION
BIOACTIVITYThe A4 lectin agglutinates A erythrocytes specifically and binds to A1 erythrocytes (273,000 sites/cell) with an association constant of 1.8 X 10(7) M-1. Although a blood group A agglutinating activity was recognized in the original preparation of V. villosa lectins, lectins with this activity were obtained in relatively small amounts from seed extracts. The predominant lectin in V. villosa seeds, B4, does not agglutinate A, B, or O erythrocytes. See: J Biol Chem 1983 Apr 25;258(8):5165-71
