New Clarity OTX Pro – Case Study: GalNAc siRNA Quantitation by SPE-LC-MS

In this webinar, we will present a solid phase extraction (SPE) method for quantifying GalNAc-conjugated siRNA in plasma and liver matrices, and will explore how optimizing key method parameters can significantly boost recovery rates and enhance analytical performance.
Key Learning Points
- Review key sample pre-treatment method strategies for the successful and improved recovery of GalNAC-conjugated siRNA in plasma and liver tissue.
- Explore how find how Clarity OTX Pro SPE strategies differ when extracting ASOs versus GalNAc-conjugated siRNA oligonucleotides.
- Learn how to choose the right Clarity OTX Pro well plate format for oligonucleotide extraction in complex matrices.
Who Should Attend
- Anyone looking to begin or improve extraction of GalNAc-conjugated siRNA duplex oligonucleotides from plasma or liver samples using solid phase extraction (SPE).
