Abstract In antisense trials, oligodeoxynucleoside phosphorothioates (S-oligo) stereoisomers arise from the thiophosphate R/S configuration. We have explored effective separation of these isomers by the combination of DEAE ion-exchange (IELC) and reversed-phase (RPLC) liquid chromatography. Twenty-six S-oligos and some of the natural counterparts were examined. In the presence of DMTr at the 5′-end, isomers could be separated well by ELC, while RPLC gave good resolution in the absence of this protecting group. Combination of these two different modes leads to more effective isolation. aDedicated to Dr. Yoshihisa Mizuno on the occasion of his 75th birthday.
