Tilt-series were acquired using ThermoFisher Titan Krios microscopes operated at 300 keV, equipped with a K3 camera and Quantum energy filter in zeros-loss mode. The energy slit width was set to 20 eV. The tilt-series were collected with serialEM using a dose-symmetric scheme, starting from 0° with a 3° tilt increment by a group of 3, with an angular range from -60° to 60°. The accumulated exposure for each tilt-series was ~120 e-/Å2, with a defocus range between -2 and -5 µm.
