Takahashi, a Howard Hughes Medical Institute investigator at Northwestern University, and senior author Marina P. Antoch at the Cleveland Clinic Lerner Research ...

Fleshing out the genome

...ins, ranked according to a functional assignment's precision and confidence. Kolker said that "a big part of this was the proteomics"-- a systematic screening and identification of proteins, in this case those which were expressed in the microbe when subjected to stress. The proteomic analyses were done by fo...
