GSLI is a family of glycoproteins with a molecular weight of approximately 114 kDa. There are two types of subunits, called A and B, with slightly different molecular weights. These subunits combine to form a tetramer structure, producing five heteroglectins. Lectins rich in A preferentially agglutinate type A red blood cells and therefore appear to be specific to α-n-acetylgalactosamine residues, while B rich lectins preferentially agglutinate type B blood cells and are specific to α-galactosamine residues. Our GSLI is a mixture of five heteroglectins. GSLI has been reported to bind a variety of glycoproteins, including laminin. Biotinylated GSLI has the right amount of biotin to provide optimal staining properties for this lectin.
