Samples were vitrified with an FEI Vitrobot IV, which was operated at 100% humidity at 4C. 2.5-3.5 ul of sample were applied to grids (Quantifoil UltrAuFoil R1.3/1.2 300 mesh gold grids ) that were glow discharged in air for 1-2 min. The sample was incubated for 30 s before blotting for 3 s with a blot force between 0 and 5.
