Comprehensive, extensible, and intelligent platform
Thermo Scientific Proteome Discoverer software is the ultimate toolbox for protein research scientists, enabling a full suite of customizable data analysis workflows for complex acquisition methods. Manage your datasets for statistical analyses, biological annotation, and data interpretation and simplify the identification and quantification of proteins in complex biological samples for a wide range of proteomics workflows. The software streamlines all major proteomics needs including peptide and protein identification, PTM analysis, isobaric mass tagging, and label-free quantitation (LFQ) from data-independent (DIA), data-dependent (DDA), and wide window (WWA) acquisitions. Achieve your goals with analysis of glycopeptides, top-down proteomics, proteoform analysis, and MS-based structural biology of chemical cross-linking XL-MS, all under the same unifying, versatile and community-enhanced protein informatics system. Proteome Discoverer software delivers comprehensive data analyses through supporting multiple database search algorithms and dissociation techniques within the same workflow.
Go beyond searching to discovering, with intelligent INFERYS™ Rescoring and the novel CHIMERYS™ intelligent search algorithm by MSAID. These innovative approaches substantially increase the identification rate, protein coverage, PTMs, and the number of unique peptide identifications enabling scientists to generate more biological insights from their existing and newly acquired data. CHIMERYS 2.0 also improves protein quantitation capabilities for isobaric mass tags as well as LFQ with DIA, DDA, and WWA acquisitions.

Comprehensive tools for proteomic studies
With a wide range of database search options and the ability to combine the output from multiple algorithms, Proteome Discoverer software increases confidence in results and decision making through cross-validation. Augment searches with intelligent INFERYS Rescoring to increase confidence in peptide identification and quantitation. Whether you acquire your data in DIA, DDA, or WWA mode, CHIMERYS 2.0 intelligent search algorithm helps you dig deeper into your data to substantially increase the number of unique peptide identifications, improve protein coverage, extend quantitation capabilities, and uncover new insights.
Complete sequence coverage and confident identification of post-translational modifications (PTMs) is realized with support for multiple dissociation techniques including collision-induced dissociation (CID), higher-energy collision-induced dissociation (HCD) and electron-transfer dissociation (ETD) in tandem with built-for-purpose search engines.
Customizable data analysis workflows
Automate and simplify data analysis through customizable workflows including full support for multiple quantitative workflows. Enjoy experimental flexibility for quantitation by employing isobaric mass tagging with TMT and TMTpro reagent or other isotopic labeling strategies or utilize label-free quantitation techniques. Map quantitative data to biological information through study management and leverage fast, robust algorithms for peak selection and peptide quantification to extract the maximum possible information from quantitative proteomics studies.
Refine acquisition strategies by generating inclusion and exclusion lists that can be directly imported into instrument methods. Confidently and easily facilitate data comparison, exchange, and verification in compliance with data standards developed by the HUPO Proteomics Standards Initiative (PSI).
