Imaging Details
For dataset 2, 410 tilt series were collected on a Titan Krios G4 instrument at 300 kV equipped with a Selectris X energy filter operating at zero-loss with a slit width of 10 eV, and a Falcon 4i camera (Thermo). Low-magnification images were taken at 11500x (object pixel size 2.13 nm) to generate lamella overviews. Tilt series were recorded at 1.89 A pixel size using the Tomography 5 (Thermo) in EER file format, with a dose-symmetric tilt scheme. The tilt series were collected with a 3 degree tilt increment with an angular range of ~120 degrees, and with cumulative dose of 80-120 electrons/A^2. Targeted defocus was in the range of -5 to -3 um.
