Webb19 mars 2024 · Cryo-EM grid preparation is an important bottleneck in protein structure determination, especially for membrane proteins, typically requiring screening of a large number of conditions. We systematically investigated the effects of buffer components, blotting conditions and grid types on the outcome of grid preparation of five different … Webb31 jan. 2024 · Proteins, interfaces, and cryo-em grids.

Webb9 okt. 2024 · Proteins rapidly frozen for cryo-EM in amorphous ice are inherently low-contrast, making them difficult to track and image. Previous work using virus particle tracking on amorphous carbon supports showed a “drum-like motion” that included deformation of the support foil and the ice layer, which together cause a rotation and … WebbGO substrates adhere macromolecules, allowing cryo-EM grid preparation with lower specimen concentrations and provide partial protection from the air-water interface. Additionally, the signal of the GO lattice beneath the frozen-hydrated specimen can be discerned in many motion-corrected micrographs, providing a high-resolution fiducial for … hafion llc
