Make advanced analytics work for your molecule
We support biotech and pharma teams working on complex modalities with ready-to-adapt workflows for high-resolution mass spectrometry analysis, including:
Peptide mapping and PTM identification
N-/O-linked glycosylation profiling
Charge variant and structural integrity assessment
Multi-Attribute Monitoring (MAM) workflows
In-process and final product characterisation
Workflows are deployable in 4–6 weeks, optimised in real regulatory conditions and fully GMP-compliant.
Science for real-world applications
Fully documented and transferable to GMP environments
Compliant with EMA & FDA regulations
Flexible for development, validation or method transfer
Direct support by scientists
Pre-established workflows for mAbs and multispecific antibodies, ADCs, fusion proteins, mRNA, AAVs
Resources at your
disposal
Access concrete examples to understand how these methods apply to your challenges:
