Synthetic glycooligomers have emerged as valuable analogues for multivalent glycan structures in nature. These multivalent carbohydrates bind to specific receptors and play a key role in biological processes. In this work, we investigate the specific interaction between mannose ligand presenting soft colloidal probes (SCPs) attached to an atomic force microscope (AFM) cantilever and a Concanavalin A (ConA) receptor surface in the presence of competing glycooligomer ligands. We studied the SCP-ConA adhesion energy via the JKR approach and AFM pull-off experiments in combination with optical microscopy allowing for simultaneous determination of the contact area between SCP and ConA surface. We varied the contact time, loading rate and loading force and measured the resulting mannose/ConA interaction. The average adhesion energy per mannose ligand on the probe was 5 kJ/mol, suggesting that a fraction of mannose ligands presented on the SCP bound to the receptor surface. Adhesion measurements via competitive binding of the SCP in the presence of multivalent glycooligomer ligands did not indicate an influence of their multivalency on the glycooligomer displacement from the ConA surface. The absence of this "multivalency effect" indicates that glycooligomers and ConA do not associate via chelate complexes and shows that steric shielding by the glycooligomers does not slow their displacement upon competitive binding of a ligand presenting surface. These results highlight the high reversibility of carbohydrate-surface interactions, which could be an essential feature of recognition processes on the cell surface.
