    • Oligonucleotide synthesis and purification: All modified oligonucleotides were synthesized on 1.3 μmol scale on Pharmacia Gene Assembler Plus DNA synthesizer. Standard DNA synthesis condition was employed, viz., CPG support and base protected 5′-O-(4,4′-dimethoxytrityl)deoxyribonucleoside-3′-[O-(diisopropylamino)-β-cyanoethylphosramidite] monomers. The phosphoramidite activated oligomer 9.12 was used at an extra monomer position, in order to introduce a guanidium linkage into Oligonucleotides. The standard synthesis cycle was modified to perform an extended coupling (15 min) during the coupling the modified phosphoramidite oligomer 9.12; a coupling efficiency of >95% was observed for this step.
