Poly-N-acetyllactosamine (poly-LacNAc) structures have been identified as important ligands for galectinmediated cell adhesion to extra-cellular matrix (ECM) proteins. We here present the biofunctionalization of surfaces with poly-LacNAc structures and subsequent binding of ECM glycoproteins. First, we synthesized β-GlcNAc glycosides carrying a linker for controlled coupling onto chemically functionalized surfaces. Then we produced poly-LacNAc structures with defined lengths using human β1,4-galactosyl-transferase-1 and β1,3-N-acetylglucosaminyltransferase from Helicobacter pylori. These compounds were also used for kinetic characterization of glycosyltransferases and lectin binding assays. A mixture of poly-LacNAc-structures covalently coupled to functionalized microtiter plates were identified for best binding to our model galectin His6CGL2
