Proteomics research. Technician using a computer to study the spots of protein produced on a 2-D gel in proteomics research. Pro- teomics is the study of the structure and function of all an organism's proteins. Proteins are separated by their charge and mass by the application of a pH gradient and an electric field respectively. Each spot contains similar proteins, which can be removed from the gel and analysed. Proteins form nearly all the functional tissues in an organism. Relating structure and function in proteins will improve understanding of how organ- isms work and may lead to new targets for drugs.
