Grids were glow discharged in air at a pressure of 2.2x10-2 Torr for 2 min at medium power with a Harrick Plasma cleaner (PDC-002). Subsequently, 3-4 ul of the sample was pipetted onto the glow discharged grids and plunge frozen in liquid Ethane with a Vitrobot IV (FEI). The sample chamber of the Vitrobot was maintained at 4C and 100% humidity. Wait time between sample application and blotting was 45 s, the drain time 0 s, the blot time 3 s and the blot force 0.. </details>
