Assessment of Biotherapeutics Quality Attributes Leveraging a Novel Fragmentation Technique

Now Available On Demand!

As the number of biotherapeutic candidates in development is increasing, the requirements of analytical tools to improve insights on the molecules early in the process are also rising. To understand product quality attributes (PQAs) fully, identification, localization and relative quantification are key. Mass spectrometry (MS) plays an important role, with peptide mapping being the gold standard to assess post-translational modifications (PTM). However, traditionally used collision-induced dissociation (CID) has several limitations in PTM identification and localization.

The novel fragmentation technique, electron activated dissociation (EAD) of the ZenoTOF 7600 system (SCIEX), was employed for peptide mapping of a multispecific monoclonal antibody (mAb) as well as IgG1 and IgG4 mAb samples. A specific focus was put on assessing challenging PTMs, such as glycosylations, amino acid isomers and the localization of a sulfation on a singly charged peptide.
