''Proteomics''&nbsp;generally denotes the large-scale experimental analysis of proteins and proteomes, but often refers specifically to&nbsp;[https://en.wikipedia.org/wiki/Protein_purification protein purification]&nbsp;and&nbsp;[https://en.wikipedia.org/wiki/Mass_spectrometry mass spectrometry]. Indeed, mass spectrometry is the most powerful method for analysis of proteomes, both in large samples composed of millions of cells<sup id="cite_ref-5">[https://en.wikipedia.org/wiki/Proteomics#cite_note-5 [5]]</sup>&nbsp;and in single cells.<sup id="cite_ref-6">[https://en.wikipedia.org/wiki/Proteomics#cite_note-6 [6]]</sup><sup id="cite_ref-7">[https://en.wikipedia.org/wiki/Proteomics#cite_note-7 [7]]</sup><br/> <br/> Full text link&nbsp;:&nbsp;[https://en.wikipedia.org/wiki/Proteomics https://en.wikipedia.org/wiki/Proteomics] === Omics === The branches of&nbsp;[https://en.wikipedia.org/wiki/Science science]&nbsp;known informally as&nbsp;'''omics'''&nbsp;are various disciplines in&nbsp;[https://en.wikipedia.org/wiki/Biology biology]&nbsp;whose names end in the suffix&nbsp;''[https://en.wiktionary.org/wiki/-omics -omics]'', such as&nbsp;[https://en.wikipedia.org/wiki/Genomics genomics],&nbsp;[https://en.wikipedia.org/wiki/Proteomics proteomics],&nbsp;[https://en.wikipedia.org/wiki/Metabolomics metabolomics],&nbsp;[https://en.wikipedia.org/wiki/Metagenomics metagenomics],&nbsp;[https://en.wikipedia.org/wiki/Phenomics phenomics]&nbsp;and&nbsp;[https://en.wikipedia.org/wiki/Transcriptomics transcriptomics]. Omics aims at the collective characterization and quantification of pools of biological molecules that translate into the structure, function, and dynamics of an organism or organisms.<sup id="cite_ref-1">[https://en.wikipedia.org/wiki/Omics#cite_note-1 [1]]</sup> The related suffix&nbsp;'''-ome'''&nbsp;is used to address the objects of study of such fields, such as the&nbsp;[https://en.wikipedia.org/wiki/Genome genome],&nbsp;[https://en.wikipedia.org/wiki/Proteome proteome]&nbsp;or&nbsp;[https://en.wikipedia.org/wiki/Metabolome metabolome]&nbsp;respectively. The suffix&nbsp;''-ome''&nbsp;as used in molecular biology refers to a&nbsp;''totality''&nbsp;of some sort; it is an example of a "neo-suffix" formed by abstraction from various Greek terms in&nbsp;-ωμα, a sequence that does not form an identifiable suffix in Greek. [https://en.wikipedia.org/wiki/Functional_genomics Functional genomics]&nbsp;aims at identifying the functions of as many genes as possible of a given organism.
