Within the biopharmaceutical industry, oligonucleotide drug pipelines have increased significantly because of the effectiveness of such drug products in treating devastating diseases. Downstream specialists need improved purification techniques for such highly valuable materials. Dimethoxytrityl (DMT) is used to synthesize oligonucleotides and temporarily mask the characteristic chemistry of the 5Í´-hydroxy functional group. DMT can be left on an oligonucleotide following synthesis to provide stability to a molecule during subsequent processing. Herein, we describe a novel, effective, and high-recovery method for purifying…
