Peptide mapping is a critical step during biotherapeutic characterization. The so-called “bottom up” characterization of biologic drugs by protein digestion to their constituent peptides is necessary to ensure a full sequence coverage of the biopharmaceutical molecule.
From drug discovery and development, through the clinical testing phase and on to bioproduction and QA/QC, peptide mapping remains a key analytical methodology. We offer a unique combination of innovative technologies in a start-to-finish workflow that is designed to be fast, reliable, reproducible and easy to use.
