WebProteins, like milk jugs, rarely orient themselves in with perfect randomness when vitrified on a cryo-EM grid. Some proteins, by virtue of their morphology (e.g., rods and discs) tend to orient with their long axis parallel to the grid. Furthermore, surface properties of both the protein and the air-water interface (AWI) create “stickiness.” WebInformation on MIT’s COVID-19 vaccination requirement can be found at the bottom of this posting.
