Sialyl Lewis X (sLeX) is a tetra-saccharide glycoconjugate of membrane proteins. It acts as a ligand for the selectin proteins during cell adhesion of inflammatory process. Aberrant overexpression of sLeX is also a characteristic of various cancer cells, especially for highly malignant ones. In this paper, the sLeX-specific RNA aptamer was selected using a random RNA library and its affinity and specificity were measured by Surface Plasmon Resonance technique.

Sialyl Lea tetra is a sialylated oligosaccharide normally occurring in human breast milk, with N-acetylglucosamine as the reducing-end residue. Sialylated oligosaccharides are important components of glycoproteins and glycolipids and also occur as free oligosaccharides in several body fluids. In human milk, both free and bound sialylated oligosaccharides have potential biological activity and are known to inhibit viral infection. Sialyl Lewis a is increasingly expressed in melanoma cells, and hypothetically immunotherapy eliciting a humoral response could be therapeutically effective against tumors.
