    • RP-HPLC analyses were performed using a 5-μm Supelcosil LC-18S column (25 cm x 4.6 mm) under the following conditions: starting from 0.1 M triethylammonium acetate pH 7.0, a linear gradient of 1% MeCN/min is pumped at a flow rate of 1 mL/min for 40 min and then held isocratic for 20 min.

    • Solid-phase synthesis of the fully phosphorothioated 20-mer requires replacing the standard iodine solution with a solution of 0.05 M 3H-1,2-benzodithiol-3-one 1,1-dioxide in MeCN and performing the capping reaction after the sulfurization step (see ref 12).

    • note
    • Since 13 and 14 are ∼60% and 100% eliminated, respectively, during each oxidation/sulfurization step of the oligonucleotide assembly, the concentrations of 13 or 14 in the simulation experiments are that of a worst-case scenario.
