... mobility is its ability to measure accurate cross sections of complex aggregations of proteins and obtain information on their three-dimensional shape. When coupled with mass spectrometry, electrospray ionization, and high-level molecular modeling, it becomes a very powerful technique. The experiment star...... To make the maps, the researchers started with sections of brain mounted on microscope slides. Those slides were scanned to create image files or "virtual slides," and assembled like tiles into composite images.
