Chromatography Experts

In this episode of Chromatography Experts, Patrick Endres of Tosoh Bioscience is joined by Steffi Stephen and Daniele Addis from Axolabs for an in-depth discussion on oligonucleotides. Together, they explore what oligonucleotides are, how they are produced, and the key steps involved in moving from synthesis to a purified therapeutic product.
The conversation covers emerging applications such as antibody-oligonucleotide conjugates (AOCs), as well as the purification and analytical challenges associated with developing oligonucleotide-based therapies. Steffi and Daniele share insights into the critical role chromatography plays in addressing these challenges.
Whether you're new to oligonucleotides or looking to expand your knowledge of this rapidly growing field, this episode offers valuable perspectives on the technologies, challenges, and partnerships driving the future of nucleic acid therapeutics.
