The blood group antigen Sialyl Lewis X (SLeX) is an oligosaccharide which plays a vital role in cell-cell recognition processes. SLeX is a terminal residue on glycolipids that are present on the surface of white blood cells and plays a key role in inflamation processes (Collins, 2006). The inital adhesion of white blood cells to a site of injury is mediated by E-selectins which specifically interact with SLeX. Cell-cell recognition between leukocytes and endothelial cells in blood is believed to occur in part through interactions between lectins and oligosaccharide ligands (Munro, 1992).
