Innovative MS Data Processing Solutions for Overcoming the Challenges of Disulfide Bond Characterization

Disulfide bonds are essential for maintaining the structural integrity, stability and biological activity of many therapeutic proteins and are therefore classified as a critical quality attribute. Identification and monitoring of expected disulfide linkages and their scrambled counterparts are key to ensuring efficacy and safety in the development of protein-based therapeutics. While spectroscopic and electrophoretic methods are available, mass spectrometry (MS)-based analysis has emerged as the predominant analytical technique.

Providing high sensitivity and detailed information at the molecular level, MS enables thorough and confident characterization of a product’s expected and scrambled disulfide linkages, but also presents several challenges such as:

• Complex data requiring extensive manual interpretation by expert users.
• A combinatorial explosion of possible candidates leading to long, indefinite data processing times.
• An extensive search space further complicated by cysteine-related linkages besides disulfides, including thioethers and trisulfide impurities.

In this webinar, learn how Genedata Expressionist offers a cutting-edge software solution designed to overcome these challenges, significantly accelerating and streamlining the in-depth characterization of disulphide linkages.
