Abstract:
:Using CPG support linked with 5-deazaflavin, the 5-deazaflavin modified oligodeoxynucleotides at 3'-end(ODN-dF1) were synthesized. The thermal stability of the duplex of ODN-dF1 with its complement was higher than that of oligonucleotide linked to 5-deazaflavin at 5'-end internucleotide linkage.
