We established a workflow for highly sensitive multiplexed quantitative phosphoproteomics using a nano-scale solid-phase tandem mass tag (TMT) labeling reactor. Phosphopeptides were firstly enriched by titanium oxide chromatography and then labeled with isobaric TMT reagents in a StageTip packed wit...
LC-MS-based profiling of proteomes with isobaric tag labeling from low-quantity biological and clinical samples, including needle-core biopsies and laser capture microdissection, has been challenging due to limited amount and sample loss during preparation. To address this problem, we developed OnM ...
Isobaric labeling is a powerful strategy for quantitative mass spectrometry-based proteomic investigations. A complication of such analyses has been the co-isolation of multiple analytes of similar mass-to-charge resulting in the distortion of relative protein abundance measurements across samples. ...
Mapping the subcellular proteome using a differential fractionation and an orthogonal nycodenz fractionation combined with quantitative mass spectrometry using isobaric labeling (TMT) in MS2
Multiplexed Data-Independent Acquisition (plexDIA) aims to bridge the gap between the quantitative depth of DIA and the sample throughput of isobaric tag-based workflows. Here, we implement non‑isobaric sample multiplexing using commercially available, isotopically differentiated tandem mass tag (TM...
Stable isotope labeling of peptides is the basis for numerous mass spectrometry-based quantification strategies. Isobaric tagging and metabolic labeling, namely TMT and SILAC, are among the most widely used techniques for relative protein quantification. Here we report an alternative, precursor-base...
Isobaric chemical tag labeling (e.g., iTRAQ and TMT) is a commonly used approach in quantitative proteomics research. Typically, peptides are covalently labeled with isobaric chemical tags, and quantification is enabled through detection of low-mass reporter ions generated after MS2 fragmentation. R...
Single cell proteomics data from three murine cell lines (Raw, SVEC4-10, C10) and HeLa cell lysate. Samples were digested with trypsin and labeled with TMT 10-Plex on a small scale using nanoPOTS, followed by LC-MS/MS analysis.
