Abstract
We evaluated size exclusion chromatography (SEC) for the detection of high-order structure of phosphorothioate oligonucleotides (PS-oligo). Because of strong interaction between PS-oligo and column packing material, peaks were broader and elution time was longer than those of the corresponding natural DNA oligonucleotides. However, single- and double-stranded structures of PS-oligo were clearly separated and discriminated, while single-stranded with high-order structures such as G-quadruplex and hairpin structure were not distinguished from each other.
