Introducing CHIMERYS 4
The all-new intelligent search algorithm for proteomics

CHIMERYS 4: a unifying, spectrum-centric search algorithm for proteomics

  • Spectrum-centric & acquisition-method agnostic (DDA, PRM, DIA)

  • Supported PTMs: Oxidation, Phosphorylation, Acetylation, Ubiquitination, unmod. Cysteines, PreOmics iST NHS

  • More than twice as fast processing for DIA data

  • Integrated into MSAID Platform and Thermo Scientific Proteome Discoverer (PD)

Delve into a wealth of information about the software's wide range of features, helpful usage tips, seamless compatibility, and effective troubleshooting solutions.

Unifying software for DDA, DIA and PRM data

  • One unifying, spectrum-centric and library-free approach for the analysis of peptide tandem mass spectra irrespective of acquisition type

  • Consistent false discovery rate estimation and post-processing, facilitating fair comparisons of DDA and DIA data

  • Label-free quantification at MS1 or MS2 level, as well as TMT™- and TMTpro™-based quantification


Now supporting PTMs for your biological R&D

  • Prediction of fragment ion intensities and retention times for unmodified, Oxidized(M), Phospho(STY), Acetyl(N-term, K), Ubiqutin(K), unmodified-Cys, Cys-Preomics iST NHS kits

  • Novel CHIMERYS-native PTM localization module based on fragment ion intensity predictions

Enhanced User Experience

  • 2x faster processing of DIA data in comparison to previous version

  • Increased computational efficiency and parallelism: accelerating time to insight for more data on the same subscription plan

  • Improved sensitivity and identification rates to dig even deeper into newly acquired and previously analyzed data

"We have been highly impressed with CHIMERYS, which allows us to now quantify >3,000 proteins from single cells. We simply widen our isolation window in a DDA workflow and let CHIMERYS do the work of confidently assigning fragment ions to multiple peptides in each MS2 spectrum.”


Ryan Kelly, PhD
BYU Department of Chemistry and Biochemistry, Provo, Utah, USA

"We are using the groundbreaking search algorithm CHIMERYS in our cutting edge single-cell proteomics platform to accurately and sensitively identify large number of peptides and proteins from our samples. CHIMERYS excites us by surpassing conventional search engines by a factor of 2.6 in terms of ID rate.”
