Multiplexed quantitative analyses of complex proteomes enable deep biological insight. While a multitude of workflows have been developed for multiplexed analyses, the most quantitatively accurate method (SPS-MS3) suffers from long acquisition duty cycles. We built a new, real-time database search (...
In the young field of single-cell proteomics (scMS), there is a great need for improved global proteome characterization, both in terms of proteins quantified per cell and quantitative performance thereof. The recently introduced real-time search (RTS) on the Orbitrap Eclipse Tribrid mass spectromet...
Isobaric tagging is a powerful strategy for global proteome profiling. A caveat of isobaric tag-based quantification is “interference” which may be caused by co-eluting peptides that are co-isolated, co-fragmented, and co-analyzed, thereby confounding quantitative accuracy. Here, we present a two-pr...
ORGANISM(S): Homo sapiens (Human) Saccharomyces cerevisiae (Baker's yeast)
Mechanistic study of H2S interference on swine, we used TMT-based comparative proteomics of lung tissues from control and hydrogen sulfide (H2S) breathing swines as a test case for evaluation of MS2, SPS MS3 and RTS-MS3 acquisition methods in both Orbitrap Fusion and Orbitrap Eclipse.
