Triple helix formation involving guanine-rich oligonucleotides is inhibited by physiological concentrations of potassium (K+). Using in vitro electrophoretic mobility shift assay (EMSA), we show that PLL-g-dex copolymer significantly stabilizes triplex structure at physiological levels of K+ that greatly inhibited triplex formation with a unmodified, guanine-rich oligonucleotide.
