Abstract
Publisher Summary Lectins are a group of nonimmunoglobulin-like proteins that exhibit a high binding specificity toward carbohydrate residues of glycoproteins and glycolipids. They have found wide application in studies on glycoproteins because they interact with carbohydrates in a highly specific manner. In spite of the ubiquitous presence of lectins in nature, only a few have been characterized to be specific for sialic acid. It has been recently demonstrated that this slug contains a lectin that is highly specific for sialic acid residues of glycoproteins. This lectin, limax flavus agglutinin (LFA), has been recently purified to homogeneity. The chapter discusses the hemagglutination assay process and the purification procedure. The macromolecular properties of LFA have been presented in the chapter in a tabular form. There is a discussion about the use of LFA–Sepharose 4B in affinity chromatography.
