Laying Out Comprehensive Characterization of a Cys-Linked ADC Using Enhanced Native MS, Middle-Down MS & Peptide Mapping Workflows
12:30 pm
- Highlighting the benefits of novel QTOF system with improved MS sensitivity using intact/native MS, subunit/middle-down MS and peptide mapping workflows in Cys-linked ADC, whilst reducing sample consumption
- Utilizing enhanced peptide mapping workflow with electron-activated dissociation to provide confident characterization across antibody sequence coverage, low-abundance impurities, PTM/payload localization, disulfide bond mapping and amino acid isomer differentiation
- Exploring intuitive tools for streamlined data analysis using a software package specifically designed for biotherapeutic characterization
