Microscopes and Mass Spectrometers [PDF]

Journal of Proteomics & Bioinformatics, 2016
Proteomics is a relatively young discipline while pathology is one of the oldest forms of scientific inquiry. These two fields have different methods and aims, but have many areas of overlap and shared interests. Cultivation of synergistic projects between physicians who study static images of disease and biologists who study the dynamic environment ...
