Immobilization strategy for construction of glycan microarrays. (a) Noncovalent, site-nonspecific attachment of glycans on the surface, (b) noncovalent, site-specific attachment of glycans on the surface, (c) covalent, sitenonspecific attachment of glycans on the surface, and (d) covalent, site-specific attachment of glycans on the surface.
