To better understand the functions of individual proteins and their place in complex biological systems, it’s necessary to measure changes in protein abundance relative to those of the system, and proteomics mass spectrometry makes that possible. Modern proteomics has shifted from its initial qualitative outlook to a continuum of qualitative and quantitative technologies and approaches which include state-of-the-art sample preparation, liquid chromatography separation, high-resolution, accurate-mass Thermo Scientific Orbitrap mass spectrometry, and proteomic software solutions for mass spectrometry data analysis.
We’re supporting successful laboratories in their discovery and study of proteomes as they combine these components into integrated workflows which maximize productivity and enable broader, deeper proteomic analysis. Our proven scientific network, publications, and pioneering solutions, driven by advances in Orbitrap mass spectrometry systems and consumables, are producing novel, stringent and reproducible results that are pushing proteomics research and discovery forward.

THERMO Scientific TSQ Altis Triple Quadrupole Mass Spectrometer
Reduce sample interference, not system efficiency

Targeted MS, and in particular selected reaction monitoring (SRM), is the quantitative analysis method of choice on the Thermo Scientific TSQ Altis Triple Quadrupole Mass Spectrometer, enabling monitoring of up to 250 peptide-specific precursor pairs (precursors and product ions) per second while using 0.2 Dalton resolution for precursor ion selection. This dramatically reduces chemical interferences while maintaining high transmission efficiency.


Thermo Scientific FAIMS Pro Duo interface
Greater proteome coverage and sensitivity

The Thermo Scientific FAIMS Pro Duo interface enhances precursor selectivity, improving qualitative and quantitative results for most peptide and protein applications while reducing time-consuming sample preparation steps. The FAIMS Pro Duo interface increases analytical performance through gas-phase fractionation and selective enhancement of peptidic compounds, reducing the complexity of MS spectra, and improving the analyte signal-to-noise ratio. The end result is greater proteome coverage, enhanced sensitivity and more accurate quantitation.
