ProteomicsGlobal quantification of intact proteins via chemical isotope labeling and mass spectrometry
Although thousands of intact proteins can be feasibly identified in recent years, global quantification of intact proteins is still challenging. Herein, we develop a high-throughput strategy for global intact protein quantification based on chemical isotope labeling. The isotope incorporation effici...

ProteomicsModulating the selectivity of affinity absorbents to multi-phosphopeptides by a novel competitive substitution strategy
Although many affinity adsorbents have been developed for phosphopeptides enrichment, high-specifically capturing the multi-phosphopeptides is still a big challenge. Here, we investigated the mechanism of phosphate ions coordination and substitution on affinity adsorbents surfaces and modulated the ...

MetabolomicsA metabolome atlas of mouse brain on the global metabolic signature dynamics following short-term fasting
Calorie restriction (CR) or a fasting regimen is considered one of the most potent non-pharmacological interventions to prevent chronic metabolic disorders, ameliorate autoimmune diseases, and attenuate aging. Despite efforts, the mechanisms by which CR improves health, particularly brain health, ar...

ProteomicsIntegrated Protein Precipitation–SPE Workflow for Deep Top-Down Proteomic Analysis of Human Serum
Top-down proteomics of human serum is hindered by extreme dynamic range and cumbersome prefractionation. Here we establish a fully solution-based protein precipitation–solid-phase extraction (PP–SPE) workflow for deep, low-molecular-weight-biased proteoform profiling. Using systematically optimized ...
