摘要

Positively charged DNG oligonucleotide mixed sequences containing A/T bases were prepared by solid-phase synthesis. Synthesis proceeds in 3'-->5' direction and involves coupling of 3'-Fmoc protected thiourea in the presence of HgCl(2)/TEA with the corresponding 5'-amine of the growing oligo chain. DNG binding characteristics with complementary DNA and with itself have been evaluated.
