The proteome unit provides comprehensive peptide and protein analyses using liquid chromatography-tandem mass spectrometry (LC/MS/MS). We offer end-to-end support tailored to each research objective, from consultation on experimental design and sample preparation to measurement and peptide/protein identification and quantification. In addition to comparative proteome profiling using data-independent acquisition (DIA), we provide post-translational modification (PTM) analyses, spatial proteomics, and protein-protein interaction analyses. Through these services, we support a deeper understanding of biological processes and accelerate drug discovery and disease research.
