Event Overview:
Oligonucleotide purification and analysis methods have grown to meet the demands of expanded pipelines for oligonucleotide therapies in recent years. In this study, we will demonstrate the effectiveness of a one-step hydrophobic interaction chromatography (HIC) method for the purification of 5′-DMT-on oligonucleotides. We will detail a method that is designed for capture, and direct on-column cleavage, of 5′-DMT-on oligonucleotides. Additionally, we will detail analytical methods including reversed phase chromatography, analytical anion exchange chromatography, and size exclusion chromatography, which will ensure the high purity and quality of the final product.

• An effective one-step purification of 5′-DMT-on oligonucleotides by hydrophobic interaction chromatography, with on-column DMT cleavage.
• The selected phenyl-phase chemistry resin has a dynamic binding capacity >45 mg/mL resin for 5′-DMT-on oligonucleotides.
• The on-column DMT cleavage method results in high product recovery while maintaining >95% product purity.

Key Learning Objectives:

• Simplify purification of 5′-DMT-on oligonucleotides using a one-step hydrophobic interaction chromatography method.
• Understand the power of hydrophobic interaction chromatography for 5′-DMT-on oligonucleotide purifications.
• Learn how to ensure the high purity and best quality of the final product.

Who Should Attend:

• Chromatographers, method developers and process engineers who are involved with the development and platform design for purification of oligonucleotides.
• Process Engineers
• Purification scientists
