Oligonucleotides

Advanced bioanalytical support for complex modalities

91黑料’s bioanalytical laboratories have built strong expertise across a broad range of analytical oligonucleotide methods, providing robust and reliable testing solutions to support the development of these advanced therapeutics throughout the different stages of clinical studies.

 

Oligonucleotide therapeutics represent a rapidly growing class of precision medicines, designed to modulate gene expression by targeting messenger RNA (mRNA) or, in some cases, DNA. These short strands of nucleic acids enable mechanisms such as gene silencing, splice correction, and mRNA degradation—unlocking therapeutic potential for previously 'undruggable' targets.

With increasing approvals and a robust pipeline across rare and common diseases, oligonucleotides are reshaping the landscape of modern drug development.

Therapeutic classes & structural complexity

Oligonucleotide drugs span a diverse range of modalities, each with unique structural and analytical challenges:

  • Antisense Oligonucleotides (ASOs)
  • Small Interfering RNAs (siRNAs)
  • MicroRNA Modulators
  • Aptamers
  • CRISPR-based Oligonucleotides

These molecules often undergo chemical modifications to enhance stability and efficacy, adding complexity to their bioanalytical evaluation.

Bioanalytical challenges in clinical trials

Oligonucleotide trials introduce novel analytical requirements that differ significantly from those for small molecules or proteins. Assays must be adapted to accurately quantify both parent compounds and metabolites using platforms such as:

  • LC-MS/MS
  • Ligand Binding Assays (LBA)
  • Polymerase Chain Reaction (PCR)

These methods must meet stringent regulatory expectations while accommodating the unique properties of oligonucleotide drugs.

Analytical platforms & methodologies

To support oligonucleotide development, a range of specialised platforms are employed:

  • Hybridisation Ligand Binding Assays
  • PCR-based methods
  • Ion Pairing (IP) LC-MS/MS, with or without Hybridisation Immunocapture (IC)

Each technique offers distinct advantages depending on the study’s objectives and molecular characteristics.
