Until now. Two laboratories recently used cryo-electron microscopy to directly image atoms in a protein molecule with a resolution of about 1.2 x 10-7 millimeters or 1.2 ångströms. The previous ...

Ribosomes are the cell’s molecular machines ... isolated RQCs from yeast cells and used cryo-electron microscopy to develop three-dimensional images of their interactions with large ribosomal subunits ...

Modifying ultracold liquid helium electron microscopy by replacing copper specimen holders with gold and reducing hole size minimizes ice expansion and movement, significantly enhancing image ...
