Quantifoil Micro Tools, Jena/Germany) were rendered hydrophilic by glow discharging in air at a pressure of 29 Pa for 2 minutes at medium power with a Plasma Cleaner (model PDC-002. Harrick Plasma Ithaca, NY/USA). Then, 3.5 ul of DHBc solution was pipetted onto the grids and they were plunge frozen in liquid ethane with a Vitrobot mark IV (FEI-Thermo Fisher Scientific). The settings for the Vitrobot were 3s blot time, 45 s wait time, blot force 0 at a temperature of 4 C and 100 % humidity
