Fast, accurate protein sequence determination
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.
Peptide mapping workflow
A significant advance in sample preparation for biopharmaceutical characterization; Thermo Scientific™ SMART Digest™ Kits utilizes immobilized trypsin for fast and simple protein digestion with high reproducibility, high sensitivity, and superior data quality in a format that's compatible with automation.
Thermo Scientific™ Acclaim™ VANQUISH™ C18 UHPLC columns are recommended for peptide mapping of biotherapeutic proteins, offering excellent separations and helping to ensure sharp peaks. These columns feature an ultrapure silica substrate with extremely low metal content to minimize tailing effects and deliver symmetrical peak shapes.
The new Thermo Scientific™ Vanquish™ Flex UHPLC platform offers the ultimate in biocompatible state-of-the-art binary or quaternary solvent blending. The Vanquish Flex platform is designed to deliver new benchmarks in accuracy, precision, and sensitivity in peptide chromatography. With rock steady retention times, you can be confident in the identity of every peptide in discovery, development and QC environments.
Seamless compatibility with both DAD, VWD, and mass spectrometric detection and fully compliant Thermo Scientific™ Chromeleon™ CDS software makes this the UHPLC system of choice for your entire drug pipeline.
Peptide mass spectrometry
One mass spectrometer for peptide mapping and intact characterization. The Thermo Scientific™ Q Exactive™ BioPharma Platform of Orbitrap-based mass spectrometers add superior denatured and native MS intact analysis and subunit top/middle-down analysis capabilities to the most powerful benchtop peptide mapping instruments available.
When combined with Thermo Scientific™ BioPharma Finder™ software it provides a complete integrated hardware and software solution for biotherapeutic characterization.
