Event Overview:

Mass spectrometry (MS)-based characterization of therapeutic proteins yields product-specific data that are leveraged throughout development to assist science and risk-based decision-making. MS-based targeted peptide mapping is a foundational technique for biotherapeutic characterization and allows relative quantitation of site-specific post-translational modifications that can be used, for instance, to assess product quality.

Recent advancements such as automated sample preparation and data acquisition have improved the overall efficiency of MS-based peptide mapping methodology. However, analysis review and reporting of the targeted peptide mapping data remains a significant bottleneck. This webinar highlights the development of automated workflows in Genedata Expressionist for targeted analysis and reporting of MS-based peptide mapping data.

The newly developed integration and processing capabilities automate several key data processing steps, which includes retrieval of sample metadata from an independent database, analysis of MS-based peptide mapping data, updates to historical MS data libraries for improved workflow performance, and export of standardized reports for subsequent large-scale data aggregation.
Discover how scientists at Janssen are leveraging customized system integration and data processing to:

  • Automate targeted MS-based peptide mapping of protein therapeutic samples
  • Drive workflow processes using sample-specific metadata
  • Standardize data reporting to enable meaningful data aggregation

Key Learning Objectives
