A 3-ul aliquot of the sample solution was applied 335to glow-discharged CryoMatrix holey grids with amorphous alloy film (Zhenjiang Lehua Technology) in 336a Vitrobot Mk IV (Thermo Fisher Scientific) at 4 degrees and 100% humidity (blot 10 s, blot force 3)..
Spike trimer (0.7 mg/ml) and Ty1 (1.3 mg/ml) were mixed 334in a 1:8 molar ratio and incubated on ice for 5 minutes.
