Mass spec method captures proteins in native membranes
Yale scientists developed a mass spec protocol that keeps proteins in their native environment, detects intact protein complexes and tracks drug binding, offering a clearer view of membrane biology.
Laser-assisted cryoEM method preserves protein structure
University of Wisconsin–Madison researchers devised a method that prevents protein compaction during cryoEM prep, restoring natural structure for mass spec studies. The approach could expand high-resolution imaging to more complex protein systems.
Method sharpens proteome-wide view of structural changes
Researchers developed a method that improves limited proteolysis coupled with mass spectrometry, separating true changes from abundance or splicing effects.
Extracellular vesicles offer clues to cattle reproduction
Extracellular vesicles from pregnant cattle support embryo development better than laboratory models, highlighting their potential to improve reproductive efficiency in bovine embryo cultures. Read more about this recent MCP paper.
Proteomics reveals protein shifts in diabetic eye disease
Using proteomics, researchers identified protein changes in eye fluid that mark diabetic retinopathy progression and may serve as biomarkers for vision-threatening complications. Read more about this recent MCP paper.
Protein modifications drive lung cancer resistance
New assay enriches protein modifications in a single process, enabling detection of key changes in drug-resistant lung cancer cells that may guide future therapies.
How antigen-processing proteins shape immunity
Researchers show how components of the antigen processing machinery shape the immunopeptidome, offering insights into immune regulation and cancer biology.
New chemical strategy boosts accuracy in proteomics
Researchers develop a methylamine-based method that nearly eliminates peptide overlabeling in proteomics, improving accuracy in protein identification and quantitation.
Mapping the placenta’s hormone network
Study uncovers how the placenta actively metabolizes not only glucocorticoids but also novel androgens and progesterones, reshaping our understanding of pregnancy and its complications.
