How does the FAIMS Pro Duo interface work?
The FAIMS Pro Duo interface is easy to set up and deploy to enhance experimental performance and is perfectly suited for nano-to-analytical flow-rate applications (up to 1000µL/min). Better selectivity means increased productivity for every user.
Conventional versus differential ion mobility spectrometry (FAIMS)
Identifying and characterizing proteins and post-translational modifications by bottom-up mass spectrometry relies on the acquisition of high-quality MS and MS/MS data. The FAIMS Pro Duo interface increases analytical performance through gas-phase fractionation and selective enhancement of peptidic compounds, reducing the complexity of the MS spectra, and improving analyte signal/noise ratio. The end result is greater proteome coverage.
Proteome analysis using the FAIMS Pro Duo interface increases proteome coverage for both low and high sample loading amounts. Comparative analysis of the number of proteins and peptides confidently identified in an analysis of a tryptic digest of HeLa cell lysate under identical chromatographic conditions. While the proteome coverage measured using the standard Data-dependent Acquisition (DDA) method at low and high sample loading amounts is impressive, simply incorporating the FAIMS Pro Duo interface substantially increased protein and peptide coverage with almost 8,000 proteins confidently measured in the 140-minute method.
Incorporation of the FAIMS Pro Duo interface into an existing DDA experimental workflow increases proteome profiling efficiency. Compared to using a standard DDA method, the FAIMS Pro Duo interface method provided similar proteome coverage while using substantially less sample and shorter chromatographic gradients, addressing the two primary concerns for translational proteomics. Comparison of protein and peptide identifications using conventional setup (control) or FAIMS Pro Duo interface (FAIMS) with 3 CVs (-50, -65, and -85 V). The addition of the FAIMS Pro Duo interface enables an improvement of 18% in protein IDs and 29% in peptide IDs when compared to not using FAIMS in DDA mode, with a 140-minute nanoflow gradient on the Thermo Scientific Orbitrap Fusion Lumos Tribrid mass spectrometer.
In this session with Dr. Michael Westphall from University of Wisconsin, Madison, learn why ion mobility isn’t what you’ve been missing for high-throughput proteomics. When Dr. Westphall connected the FAIMS Pro interface with our LCMS systems, it enabled him to obtain up to a 20% or more increase in the number of proteins and peptides detected.
Dr. Devin Schweppe of Harvard Medical School discusses the Thermo Scientific FAIMS Pro interface for improved quantitative accuracy and peptide quantitation.
