From Genome to Proteome: Looking at a Cell's Proteins

Heidelberg, Germany—It sounds like Mission Impossible: Follow the changes taking place in a cell by identifying the thousands of different proteins the cell produces and watching how they ebband flow over time. But a growing band of researchers believes that improved analytical techniques may soon make such an approach feasible, and they haveeven coined a new term for it: proteome research. Prototype systems that screen and analyze thousands of proteins at a time look promising.
