AI Article Synopsis

  • Therapeutic oligonucleotides have gained regulatory approval in key regions like the US, EU, and Japan, highlighting their significance in drug development.
  • Liquid chromatography techniques are essential for ensuring the purity and quality of these oligonucleotides.
  • In a study on ion-pair reversed-phase separation, various factors such as stationary phase pore size, mobile phase additives, and column temperature were analyzed, showing their impact on the separation process and potential optimization strategies.

Article Abstract

Therapeutic oligonucleotides have recently been approved in the United States, the EU, and Japan. Hence, the analysis of oligonucleotides is an important topic in drug development. Liquid chromatographic techniques are commonly used for purity verification and the determination of oligonucleotides. In ion-pair reversed-phase separation, several parameters, such as the pore size of the stationary phase, mobile phase additives, and column temperature, were investigated using three types of oligonucleotides (18, 19, and 20 mer). All of the investigated parameters could influence the separation, and they are expected to be useful for optimizing oligonucleotide separation.

The increased effectiveness of small interfering RNAs (siRNAs) to induce gene silencing has brought a great therapeutic promise to many diseases. siRNAs are under highly active current research and development. Ligand conjugation and chemical modifications of the sense (SS) and antisense (AS) strands of the siRNA duplex improve stability and facilitate delivery, but significantly increase the complexity of the analytical requirements.

In indirect detection, sample components lacking detectable properties are detected by adding a detectable component to the eluent, a so-called probe that interacts with the analytes to be detected. This study focuses on modeling indirect detection in two principally different cases. In case (1), the analyte component has the same charge as the probe component, so the probe acts as a co-ion of the analyte.

The use of liquid chromatography coupled with mass spectrometry (LC-MS) for the characterization of oligonucleotides and nucleic acids is a powerful analytical method. Recently, hydrophilic interaction chromatography (HILIC) has been proposed as a reasonable alternative to ion-pair reversed phase separations of oligonucleotides prior to MS. A wide variety of HILIC stationary phase surface chemistries are currently available.

Ion-pair reversed-phase liquid chromatography (IP-RPLC) is clearly recognized as the gold standard for analyzing therapeutic oligonucleotides (ONs). Recent studies have shown that ONs exhibit an on-off retention behavior in IP-RPLC, meaning that minor changes in acetonitrile (ACN) proportion can significantly impact retention. However, this behavior was initially demonstrated with only a single mobile phase condition.

Article Synopsis
  • Rapid advancements in mRNA technology require new analytical techniques, leading to the development of a novel method using ion-pair reversed-phase liquid chromatography with high-resolution mass spectrometry (IP-RP-LC-HRMS) to analyze poly(A) and poly(T) tail lengths in mRNA's DNA template.
  • The study involved validating the poly(A) tail length via Sanger sequencing, amplifying double-stranded DNA using PCR, and confirming sample quality through gel or capillary electrophoresis before extracting and analyzing the tails with LC-MS for precise length determination.
  • The results showed that while LC-MS correlated well with Sanger sequencing, it also detected unexpected minor populations of poly(A) tails of varying lengths, suggesting potential
