Overview
Keep with the pace of next generation drug development.
Subunit mass analysis can be used as a screening tool for candidate developability, identity and quality. This approach addresses the need for fast and intuitive characterization of therapeutic proteins in early development to not only ensure drug efficacy and safety, but to quickly distinguish post-translational modifications (PTMs) and drug conjugation sites.
Novel, time-saving strategies for monoclonal antibody (mAb) subunit protein analysis provide in-depth PTM information and leverage high-quality data to develop routine and reproducible workflows from discovery through commercialization.
Workflow
Rapid middle-down protein analysis
Make decisions on candidate developability or product quality sooner.
A challenge in rapid characterization of therapeutics is obtaining high sequence coverage and in-depth information on PTM localization while minimizing sample preparation artifacts like undesired modifications or loss of information on complex therapeutics like antibody drug conjugates.
Subunit mass analysis strategies – such as middle down mAb fragment analysis, can be employed to address these challenges.
A single-injection, EAD-based, middle-down workflow for subunit mass analysis leverages information-rich and reproducible EAD fragmentation with automated data analysis to consistently deliver high sequence coverage of mAb subunits and enable confident sequence and PTM confirmations.
Solution
- In-depth characterization of mAb subunits
- Rapid PTM localization
