A series of mono- or disaccharide-protein conjugates were prepared by amide bond formation. Incorporation efficiency of the aminosaccharides on bovine serum albumin was determined by colorimetry and matrix assisted laser desorption/ionization mass spectrometry. Study compares two amide bond coupling agents, 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride and 4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium chloride. Paper demonstrates a practical usefulness of natural bovine serum albumin succinylation. Large number of its carboxyl groups results in its superior reactivity towards simple aminosaccharides.
