For cryo-EM, samples were chemically stabilized by fixation in glycerol gradients with increasing concentrations of glutaraldehyde (0-0.1%). Peak gradient fractions (~0.2 mg/mL) containing glutaraldhyde were quenched upon the addition of 50 mM Tris-HCl (pH 7.5) before flash-freezing and storage under liquid nitrogen.
