Proteomic analyses have proven to be an invaluable tool in obtaining high—throughput protein identification from low—abundance, complex biological samples. In Organelle Proteomics, detailed prools provide step—by—step instructions to successfully study organelle proteomes by performing the purification of the various organelles present in eukaryotic cells, as well as by preparing certain sub—fractions of organelles. A series of chapters cover the whole analytical procedure of organelle characterization, from its purification starting with whole cells up to protein identification using mass spectrometry. Devoted to methods enabling a global estimate of the reliability of the protein list assigned to an organelle, Organelle Proteomics allows scientists to gain a vital and important understanding of organelle study.
