In 1998, the US Food and Drug Administration (FDA) approved fomivirsen as the first therapeutic oligonucleotide therapeutic. This approval marked a revolution of mechanism of action discovered decades before finally coming to fruition. Since then, the landscape of chemical modifications of oligonucleotides, conjugations and formulations has evolved tremendously, contributing to improvements in stability, efficacy and safety. Today, more than a dozen antisense oligonucleotides (ASOs) and small interfering RNA (siRNA) drugs are on the market, most of which are designated as orphan drugs for treating rare genetic diseases.

The whys behind the dos and don’ts of oligonucleotide analysis
We know that LC-MS oligonucleotide analysis can have its share of challenges—challenges with sensitivity, challenges with adduct formation and challenges with data analysis, to name just a few. That’s why this blog takes a closer look at the dos and don’ts of this type of analysis and explores some keys to success. It also explains why following these simple rules can vastly improve your oligonucleotide characterization and quantitation efficiency and success.
