ProteomicsIntensity-based label-free proteomics using a quadrupole orbitrap mass spectrometer
We present a unique data set for benchmarking label free quantitative proteomics using a quadrupole orbitrap mass spectrometer. Soluble Escherichia coli digest was spiked into a HeLa digest in four different concentrations, simulating protein expression differences. The data set, which is available ...

ProteomicsTriggered offset fragmentation allows massively multiplexed target profiling on quadrupole-orbitrap mass spectrometers
Parallel reaction monitoring (PRM) on quadrupole-orbitrap mass spectrometers has a limited multiplexing capacity which depends heavily on the reproducibility of peptide retention times. To overcome these limitations, we aimed to establish a data acquisition mode that allows retention-time-independen...

ProteomicsThe Q Exactive HF, a Benchtop Mass Spectrometer with a Pre-filter, High Performance Quadrupole and an Ultra-High Field Orbitrap Analyzer
The quadrupole Orbitrap mass spectrometer (Q Exactive) has made a powerful proteomics instrument available in a benchtop format. It significantly boosted analyzable proteins per hour and has now evolved into a proteomics analysis workhorse for many laboratories. Here we describe the Q Exactive Plus ...

ProteomicsA Compact Quadrupole-Orbitrap Mass Spectrometer with FAIMS Interface Improves Proteome Coverage in Short LC Gradients
State-of-the-art proteomics-grade mass spectrometers can measure peptide precursors and their fragments with ppm mass accuracy at sequencing speeds of tens of peptides per second with attomolar sensitivity. Here we describe a compact and robust quadrupole-orbitrap mass spectrometer equipped with a f...
