In 1988, Herman Stillmark discovered a hemagglutinin (that he originally called ricin) in extracts of castor beans. Although lectins were rst described in plants in relation to their cell agglutinating properties [1,2], molecules that bind carbohydrate residues have now been discovered in viruses, microorganisms, plants, and animals [1,3,4]. It has been shown that lectins serve to mediate diverse carbohydrate recognition events in plants and animal tissues of both embryonic and adult origins.
