Notes:
- All codes need to be in a parenthesis, except A, C, G, T (for DNA), rA, rC, rG, rU (for RNA), mA, mC, mG, mU (for 2′-OMe), and fA, fC, fG, fU (for 2′-F). For example: (LNA-A)AmC fGrU(dU) (mT)*(moeA)(cetG) (FANA-C)(GNA-A)(fAs)* (5Me-dC)(G-Mesyl)A
- The default backbone linkage between two modification codes is phosphodiester, except * for phosphorothioate and dithiophosphate, e.g., GCT (dAs)*C*G* TCA and ^ for linkage made by post-synthesis conjugation, e.g., (TCO-N)^(C6NH2)A CGT.
