Innovative ICP-MS/MS approach for the determination of phosphodiester to phosphorothioate ratio in phosphorothioate oligonucleotides

Phosphodiester to phosphorothioate ratio (P=O/P=S) is a critical quality attribute of phosphorothioate oligonucleotides. The determination of this ratio is commonly performed by 31P-NMR, which requires specific equipment and cannot be easily applied in a regulated (GxP) environment.

Stress testing of Humira (adalimumab) monitored by Hydrogen-Deuterium Exchange Mass Spectrometry (HDX-MS)

In this application note, we present how this technology can be used to monitor structural changes at the amino acid level during stress testing studies of a monoclonal antibody. This appreach can be applied similarly to stability studies.
