A surface plasmon resonance (SPR) based natural glycan microarray was developed for screening of interactions between glycans and carbohydrate-binding proteins (CBPs). The microarray contained 144 glycan samples and allowed the real-time and simultaneous screening for recognition by CBPs without the need of fluorescent labeling. Glycans were released from their natural source and coupled by reductive amination with the fluorescent labels 2-aminobenzamide (2AB) or anthranilic acid (AA) followed by high-performance liquid chromatography (HPLC) fractionation making use of the fluorescent tag. The released and labeled glycans, in addition to fluorescently labeled synthetic glycans and (neo)glycoproteins, were printed on an epoxide-activated chip at fmol amounts. This resulted in covalent immobilization, with the epoxide groups forming covalent bonds to the secondary amine groups present on the fluorescent glycoconjugates. The generated SPR glycan array presented a subset of the glycan repertoire of the human parasite Schistosoma mansoni. In order to demonstrate the usefulness of the array in the simultaneous detection of glycan-specific serum antibodies, the anti-glycan antibody profiles from sera of S. mansoni-infected individuals as well as from non-endemic uninfected controls were recorded. The SPR screening was sensitive for differences between infection sera and control sera, and revealed antibody titers and antibody classes (IgG or IgM). All SPR analyses were performed with a single SPR array chip, which required regeneration and blocking of the chip before the application of a serum sample. Our results indicate that SPR-based arrays constructed from glycans of natural or synthetic origin, pure or as mixture, can be used for determining serum antibody profiles as possible markers for the infection status of an individual.
