Proteomics in drug discovery.
The promise of genomics has dramatically altered the way drug discovery is now viewed. Overshadowed by the exuberance for genomics are the observations that most disease processes and treatments are manifest at the protein level and that there may not be a good correlation between gene expression and protein expression. An alternative and complementary approach to genomics is protein expression profiling - proteomics. The authors describe the technology, its advantages and some applications.
