ProteomicsA Collision-induced Dissociation Cleavable Isobaric Tag for Peptide Fragment Ion-based Quantification in Proteomics
Fragment ion-based proteome quantification methods quantify peptides based on unique peptide fragment ions avoiding the issue of ratio distortion that is commonly observed for reporter ion-based quantification approaches. Herein, we present a novel approach that relies on a collision-induced dissoci...

ProteomicsExtending the Separation Space with Trapped Ion Mobility Spectrometry Improves the Accuracy of Isobaric Tag-based Quantitation in Proteomic LC/MS/MS
Two-dimensional separation by nano-LC and trapped ion mobility spectrometry (TIMS) prior to Q-TOF tandem mass spectrometry significantly improves the accuracy of isobaric tag-based quantitation in proteome analysis without the need for additional measurement time for TIMS insertion. The obtained pea...

ProteomicsRatio accuracy evaluation and correction using tandem mass tags
The multiplexing capabilities of isobaric mass tag based protein quantification, such as Tandem Mass Tags (TMT) or Isobaric Tag for Relative and Absolute Quantitation (iTRAQ) have dramatically increased the scope of Mass Spectrometry (MS) based proteomics studies. Not only does the technology allow ...

ProteomicsTMTpro: Design and initial evaluation of a novel Proline-based isobaric 16-plex Tandem Mass Tag reagent set
The design and synthesis of a novel proline-reporter-based isobaric Tandem Mass Tag 16 tag set (TMTpro) was carried out and the data uploaded here is a comparison of the performance of the new TMTpro tags with the current commercially available dimethylpiperidine-reporter-based TMT10/11 reagents. Da...

ProteomicsmTMT: An alternative, non-isobaric, tandem mass tag allowing for precursor-based quantification
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...

ProteomicsAssessing Interference in Isobaric Tag-based Sample Multiplexing using an 18-plex Interference Standard
Reporter ion interference remains a limitation of isobaric tag-based sample multiplexing. Advances in instrumentation and data acquisition modes, such as the recently developed real-time database search (RTS), can reduce interference. However, interference persists as does the need to benchmark upst...

ProteomicsEASI-tag enables accurate multiplexed and interference-free MS2-based proteome quantification
We developed EASI-tag (Easily Abstractable Sulfoxide-based Isobaric tag), a new generation of amine-derivatizing and sulfoxide-containing isobaric labelling reagents, which dissociate at low collision energy and generate peptide-coupled, interference-free reporter ions with high yield. Efficient iso...
