Prep-LC MS/UV in Combination with Improved IP-RPLC Chromatography for the Purification of Oligonucleotides

In this study, the automatized Agilent 1290 Infinity II system was used for purification of native single stranded oligonucleotides (ONs). The separations were performed with IP-RPLC using dibutylamine (DBA) and tris(hydroxymethyl) aminomethane (TRIS). The combined separation methods with instrumental setup with columns, allowed for the target compound to be collected faster and with higher purity, compared to conventional methods.
