MetabolomicsCharacterization of the Human Exposome by a Comprehensive and Quantitative Large-Scale Multianalyte Metabolomics Platform
The exposome, defined as the cumulative measure of external exposures and associated biological responses throughout the lifespan, has emerged in recent years as a cornerstone in biomedical sciences. Metabolomics stands out here as one of the most powerful tools for investigating the interplay betwe...

MetabolomicsQuantitative metabolomics of plasma and tissue interstitial fluids from mice

This study presents quantitative metabolomic measurements of plasma and tissue interstitial fluids (IF) collected from healthy C57BL/6J mice. Using liquid chromatography–mass spectrometry (LC–MS) and external chemical standards, absolute concentrations were determined for over one hundred polar m...

MetabolomicsMatrix Effect on Chemical Isotope Labeling and Its Implication in Metabolomic Sample Preparation for Quantitative Metabolomics
Matrix effect from various constituents in biological samples can reduce the accuracy of quantitative metabolomics. Differential chemical isotope labeling liquid chromatography mass spectrometry (CIL LC-MS) can overcome the matrix effect on MS detection based on measuring the intensity ratios of met...

ProteomicsImpact of Sample Preparation Strategies on The Quantitative Accuracy of Low-Abundance Serum Proteins in Shotgun Proteomics
Serum proteomics plays a crucial role in biomarker discovery and disease research, yet the selection of an optimal sample preparation method remains challenging. Evaluating the accuracy of protein quantitation is of major importance and a vital part of a benchmarking study in proteomics, since clini...

ProteomicsQuantitative accuracy and precision in multiplexed single-cell proteomics.
Multiplexed quantitative mass spectrometry-based proteomics is shaped by numerous opposing propositions. With the emergence of multiplexed single-cell proteomics, studies increasingly present single cell measurements in conjunction with an abundant congruent carrier to improve precursor selection an...

TranscriptomicsQuantitative assessment of single-cell RNA sequencing methods
We generated single-cell transcriptomes from a large number of single cells using several commercially available platforms, in both microliter and nanoliter volumes, and compared performance between them. We benchmarked each method to conventional RNA-seq of the same sample using bulk total RNA, as ...

ProteomicsDeuterium-free, Three-plexed Peptide Di-Ethylation for Highly Accurate Quantitative Proteomics
The deuterium, frequently used stable isotope in isotopic labeling for quantitative proteomics, could deteriorate the accuracy and precision of proteome quantification owing to the retention time shift of deuterated peptides from the hydrogenated counterpart. Herein, we introduce a novel three-plexe...

TranscriptomicsA quantitative model of transcription regulation reveals the role of non-conserved enhancers
We identify sites of combinatorial control by performing high throughput ChIP experiments on p300, CREB-binding protein (CBP), the deacetylase SIRT1 and on multiple DNA-binding transcription factors in three different tissues. We present a quantitative model of transcriptional regulation that revea...
