Construction of heparan sulfate microarray for investigating the binding of specific saccharide sequences to proteins.

ABSTRACT: Heparan sulfate (HS) is a heterogeneous, extracellular glycan that interacts with proteins and other molecules affecting many biological processes. The specific binding motifs of HS interactions are of interest, but have not been extensively characterized. Glycan microarrays are valuable tools that can be used to probe the interactions between glycans and their ligands while relying on relatively small amounts of samples. Recently, chemoenzymatic synthesis of HS has been employed to produce specific HS structures that can otherwise be difficult to produce. In this study, a microarray of diverse chemoenzymatically synthesized HS structures was developed and HS interactions were characterized. Fluorescently labeled antithrombin III (AT) and fibroblast growth factor-2 (FGF2) were screened aga
