Abstract
Perbenzoylated sialooligosaccharides were found to be stable derivatives, giving intense signals during the matrix-assisted laser desorption/ionization (MALDI) mass spectrometric analysis in the positive-ion mode. Terminal Neu5NAcα2→3 and α2→6Gal units of oligosaccharides undergo characteristic structural changes during benzoylation, yielding easily recognizable mass spectral patterns. Subpicomole carbohydrate samples were successfully benzoylated and analyzed through MALDI mass spectrometry.
