Genomes and Proteomics—Unlocking the secrets of life

Contact us: 509-375-3776

Recent contributions by PNNL researchers to the field of proteomics include development of sophisticated new instruments and the most complete proteome identification to date of a living organism—more than 1,900 proteins in a radiation-resistant microbe. Scientists hope that understanding proteins will lead to knowledge of how the body repairs itself, why the repairs don't always work and eventually how to prevent health problems, such as breast cancer and heart disease.
