Proteomics true Top-down proteomics Quantitative proteomics Proteomics uses any methods (especially high-throughput) that separate, characterize and identify proteins: mass spectrometry, two-dimensional gel electrophoresis and protein microarrays, as well as in-silico methods that perform proteolytic or mass calculations on a protein sequence and other analyses of protein production data, for example in different cells or tissues. Style of definitions, 2 different tries: compare this kind of definition with the one in Metaproteomics. Another alternative here: leave just the broad definition, and leave the narrow one as a comment. 2025-11 Matúš Kalaš Proteomics is in the narrow sense (sensu stricto) the application of methods to separate, characterise, identify, and quantify all proteins (the proteome) - or a substantial set of proteins - that are present in a sample. Proteomics in the broad sense is the science of proteins and peptides on the large scale. Bottom-up proteomics Proteomics beta12orEarlier Omics
