title: Enantioseparation using cyclosophoraoses as a novel chiral additive in capillary electrophoresis.
abstract: Cyclosophoraoses, cyclic beta-(1-->2)-D-glucans produced by Rhizobium meliloti 2011, were used as a novel chiral additive for the separation of terbutaline, amethopterin, thyroxine and N-acetylphenylalanine enantiomers in aqueous capillary electrophoresis (CE). Enantioseparation took place in the normal- or reversed-polarity mode when a high concentration of neutral (60 mM) or anionic (40 mM) cyclosophoraoses was added to the background electrolyte (BGE).
