ProteomicsDetecting single amino acids and small peptides by combining isobaric tags and peptidomics
Single amino acids and small endogenous peptides play important roles in maintaining a properly functioning organism. These molecules are however currently only routinely identified in targeted approaches. In a small proof-of-concept mass spectrometry experiment we found that by combining isobaric t...

ProteomicsHuman CSF peptidomics of gamma secretase inhibition
Fifteen human healthy volunteers, divided into three groups, received a single dose of placebo or either 140 mg or 280 mg of the γ-secretase inhibitor semagacestat (LY450139). Endogenous peptides in CSF, sampled prior to administration of the drug and at six subsequent time points, were analyzed by ...

ProteomicsAn intelligent Boosting to Amplify Signal with Isobaric Labeling (iBASIL) strategy for precise quantitative single-cell proteomics
Mass spectrometry (MS)-based proteomics has great potential for overcoming the limitations of antibody-based immunoassays for antibody-independent, comprehensive, and quantitative proteomic analysis of single cells. Indeed, recent advances in nanoscale sample preparation have enabled effective proce...

ProteomicsA Triple Knockout (TKO) Proteomics Standard for Diagnosing Ion Interference in Isobaric Labeling Experiments
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. ...

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...

ProteomicsA Signal Amplification via Boosting with Isobaric Labeling Strategy for Comprehensive Quantitative Phosphoproteomic Characterization of Small Populations of Cells
Despite recent advances in MS-based proteomics, comprehensive phosphoproteomics analysis of small populations of cells remains a daunting task, due primarily to the general lack of sufficient MS signals from such limited amounts of samples. In light of the unique multiplexing feature of isobaric lab...
