Researchers rely on supercomputers that use many processors working in parallel. In the Cianfrocco lab, for example, were using cryo-EM to look at the dynamic process of how molecular motors move along microtubular tracks inside cells. To obtain an image using cryo-EM, researchers take proteins that have been biochemically purified from cells and instantaneously freeze the sample on a cryo-EM grid at -180 degrees Celsius. Second, electron microscopes can't be used on anything that's in water, since the process evaporates that water. What is cryo-electron microscopy, the Nobel prize-winning technique? used cryo-electron microscopy (cryo-EM) to infer the structure of FERRY and the molecular features that allow the complex to bind to both EEs and mRNAs . Because the wavelength of electrons is 100,000 times smaller than that of light, the particles reveal even the tiniest of structures. But since the proteins in his sample happened to be oriented in the same direction, Henderson was able to compile the fuzzy images from each protein in the membrane to generate one sharper image.
