Waters is introducing new SPE sample preparation kits for oligonucleotide bioanalysis that demonstrate improved recovery and reproducibility using a standardized detergent-free protocol that minimizes method development, is automation friendly and works across a diverse range of oligonucleotide therapeutics. The webinar covers the challenges when establishing an oligonucleotide quantitation workflow and how they are addressed using this new SPE kit-based approach.

This app note reviews the development of the OligoWorks SPE Microplate Kit and detergent-free protocol for oligonucleotide bioanalysis and demonstrates performance across a broad range of chemically diverse oligonucleotides, including GalNAc and lipid-conjugated species. The analytical testing and screening work to optimize the protocol for high recovery and low matrix effects is discussed in detail and LC-MS data is presented for spiked plasma and urine samples showing excellent inter and intra-kit, day-to-day and user-to-user reproducibility (RSDs ≤15%).

This app note demonstrates automation of the OligoWorks SPE Microplate Kit and protocol using the Andrew + pipetting robot and presents quantitative LC-MS data across a diverse set of oligonucleotide therapeutics spiked into plasma. Quantitative LC-MS results from the automated detergent-free workflow are compared to results from manual processing demonstrating equivalent performance as well as excellent reproducibility, underscoring the benefits of automating the OligoWorks SPE Microplate Kit: a streamlined sample extraction workflow, reduced errors, reproducible analytical method performance and enhanced lab productivity.
