Comparison of single-particle reconstructions obtained from conventional and revitrified cryo samples. (a) Reconstructions of apoferritin from a conventional cryo sample (left, 4.57 Å resolution) and a melted and revitrified cryo sample (right, 4.25 Å resolution). Details are shown for the densities of an α-helix that has been fitted with PDB entry 6v21 (Wu et al., 2020). (b) Single-particle reconstructions of CCMV from a conventional cryo sample (left, 4.98 Å resolution) and a melted and revitrified cryo sample (right, 5.20 Å resolution). Details of the densities of the capsid are shown in the vicinity of the quasi-threefold symmetry axis. The densities have been fitted with PDB entry 1cwp (Speir et al., 1995). The structures obtained from conventional and revitrified samples are indistinguishable within the resolution of our instrument. |
