It was observed that conjugation of dextran for PLL provided PLL-g-Dex with new properties of enhancing and accelerating inter-nucleotide recognition (1, 2, 3). In this paper, we report the effects of cationic PLL-g-Dex copolymers on base-pair formation of self-complementary octamer oligonucleotide by using NMR and CD analysis. NMR studies revealed that PLL-g-Dex copolymer did not affect hydrogen-bondings between bases in DNA duplex. CD studies also supported inert nature of the copolymer upon hybrid structure.
