Efficient solid-phase synthesis of trifunctional probes and their application to the detection of carbohydrate-binding proteins.

[structure: see text] An efficient solid-phase synthesis of trifunctional probes containing a photoreactive group, a reporter tag, and a carbohydrate ligand was developed. Labeling studies with these probes demonstrate that specific lectins can be labeled with high sensitivity and selectivity. This technique serves as a powerful tool for the rapid detection and profiling of lectins.
