Abstract
Over the past few years, intercalated motifs (i-motifs) have attracted attention due to the direct visualization of their existence in the nuclei of human cells. Traditionally, i-motifs have been studied using expensive and complicated NMR, and/or relatively inexpensive but less common circular dichroism spectrometry. The aim of this study was to investigate the feasibility of using less expensive, less complicated, and more widely available CE as an alternative for i-motif related research. The mobilities of two DNA and RNA i-motifs in CE were determined under different pH conditions. Our results demonstrate that CE is able to identify and differentiate mostly folded, partially folded, and mostly unfolded DNA and RNA i-motifs through changes in peak shape and migration time, thus providing a new method to study both i-motif conformation and the interactions between i-motifs and their ligands.
