disulfide-linked d(S-TGCGAATTCGCT-S/S-TCGCTTAAGCGT-S)
disulfide-linked d(s-tgcgaattcgct-s/s-tcgcttaagcgt-s)
A cyclic oligonucleotide consisting of TGCGAATTCGCT and TGCGAATTCGCT strands of DNA linked by hydrogen bonding between the base pairs and also covalently via two disulfanediyldiethane-1,2-diyl linkages between the N-3 atoms of the terminal thymidine residues.
