MetabolomicsIntegrating two chromatographies in a co-fractionation mass spectrometry approach improved protein-metabolite interactions (PMIs) mapping capabilities and revealed novel protein-ligand pairings in Escherichia coli.
The protein-metabolite interactome remains understudied. We previously developed a co-fractionation mass-spectrometry-based approach called PROMIS to address this gap. PROMIS relies on size separation chromatography of protein-metabolite complexes from lysates, followed by proteomics and metabolomic...

ProteomicsComparison of fractionation proteomics for local SWATH library building
For data-independent acquisition by means of sequential window acquisition of all theoretical fragment ion spectra (SWATH), a reference library of data-dependent acquisition (DDA) runs is typically used to correlate the quantitative data from the fragment ion spectra with peptide identifications. Th...

ProteomicsImproved detection of tryptic immunoglobulin variable region peptides by chromatographic and gas-phase fractionation techniques.
Circulating antibodies provide valuable information about an individual’s immune status and constitute a significant portion of the human plasma proteome. Proteomic analysis of plasma is challenged by the large dynamic concentration range of plasma proteins, including antibodies. Peptide fractionati...
