A new, efficient, and mild protocol is presented for the coupling of saccharides to proteins. First, a heterobifunctional aminooxy-thiol linker is coupled to the bromoacylated protein to introduce aminooxy groups through thioether linkages. Condensation of the aminooxylated protein and aldehydo/keto-derivatized carbohydrates affords covalent saccharide−protein constructs. Uncoupled saccharide can be
