RP-HPLC profile of unpurified of 2′-OMeUtaPS. RP-HPLC analysis is performed employing a 5-μm Phenomenex Jupiter C-4 HPLC Column (25 cm × 4.6 mm) under the following chromatographic conditions: starting from 0.1 M ammonium acetate in 1:1 (v/v) water/acetonitrile, a gradient of acetonitrile is pumped at a flow rate of 1 mL/min to 100% acetonitrile over a period of 20 min.
