Standardized workflow for precise mid- and high-throughput proteomics of blood biofluids
The Van Eyk group presents a standardized workflow for precise high-throughput proteomics of blood biofluids using the 60 SPD method. They established optimal conditions for sample preparation and DIA analysis in plasma, then automated and adapted this for depleted...Integrative analysis of cell state changes in lung fibrosis with peripheral protein biomarkers
In this study, the Theis and Schiller groups at the Helmholtz Zentrum München, investigated the correspondence of cell state changes in diseased organs to peripheral protein signatures in pulmonary fibrosis patient cohorts. From plasma proteome profiling of more than...Evosep One facilitates rapid and comprehensive maps of the subcellular proteome and phospho-proteome dynamics
Dynamic change in subcellular localization of signaling proteins is a general concept that eukaryotic cells evolved for eliciting a coordinated response to stimuli. Mass spectrometry (MS)-based proteomics in combination with subcellular fractionation can provide comprehensive maps of spatio-temporal regulation of cells, but involves laborious workflows that does not cover the phospho-proteome level.
Breakthrough paper by the Mann group demonstrates trat true single-cell proteomics is now a reality to address important questions in cell biology
Single-cell technologies are revolutionizing biology but have so far mainly been limited to imaging and deep sequencing. However, proteins are the main drivers of cellular function and in-depth characterization of individual cells by mass spectrometry (MS)- based proteomics would thus be highly valuable and complementary.
