The study of gene expression at the protein level, by the identifying and characterizing proteins present in a biological sample. By comparing samples from healthy and diseased tissues, it is possible to identify proteins that are specific to diseased cells. These may be potential diagnostic markers for particular diseases, or targets for drug development. Unlike the genome, which is constant regardless of cell type, the proteome varies in each cell type.
