Key benefits
- Complete sequence coverage peptide map of monoclonal antibody
- Confident detection of inter- and intrachain disulfide bonds
- Sensitive detection of low-level post-translational modifications (PTMs) with excellent mass accuracy
Goal
Demonstrate the utility and capability of the Thermo Scientific™ Orbitrap Exploris™ 240 mass spectrometer for the routine characterization of biotherapeutics through LC-MS peptide mapping. Provide the analyst with full sequence coverage, high confidence in low level PTM assignment through high-resolution accurate-mass (HRAM) MS/MS identification and overall ease in the interpretation of complex data.
