Mini webinar: Analytical approaches for quantitative determination of therapeutic oligonucleotides from biological samples

Analysis of oligonucleotides from biological samples is a challenging task. Due to the heterogeneous nature of the analytes, currently no generic bioanalytical approach is available to cover all the different therapeutically relevant oligonucleotide classes.

Bioanalysis is mainly conducted by LC/MS, hybridization-ELISA assay, qPCR, or AEX-HPLC with fluorescence detection. Depending of the analytical technique and the biological matrix, the extraction procedure is the most critical step. Here a comparison of the different methodologies used for the bioanalysis of oligonucleotides is shown, with a special focus on the properties of the PNA-HPLC assay that combines competitive sensitivity with an extraction free sample preparation procedure.

What will you learn?

  • Analytical techniques suitable for bioanalysis of short oligonucleotide sequences
  • Applications of the PNA-HPLC assay for oligonucleotide bioanalysis

Who may this interest?

  • Scientists working in Pharma/Biotechs/Academia with oligonucleotide therapeutics
  • Scientist in DMPK
