Image of phosphorus-containing macromolecular assemblies in the cell nuclei of drosophila larvae; dual-axis EFTEM tilt series acquired with a Tridiem energy filter from -66˚ to 66˚; for each axis phosphorus L-23 series (20 eV slit, pre-edge and post-edge) were collected; a jump-ratio series was calculated and the data were aligned and reconstructed using IMOD (University of Boulder, Colorado); finally, the reconstruction was rendered in the 3D visualization software; the inset highlights a sub-volume extracted using the 3D visualization ROI tool.

Image of interplanetary dust particle; STEM tilt series acquired with a 806 HAADF detector from -61˚ to 68˚; aligned, reconstructed and visualized using 3D reconstruction and 3D visualization software; the iso-surfaces highlight two different intensity levels in the reconstruction.

First 3.2 Å β-galactosidase structure solved by cryo-EM

First 3.2 Å β-galactosidase structure solved by cryo-EM
Bartesaghi, A.; Matthies, D.; Banerjee, S.; Merk, A.; Subramaniam, S.

Structure of Escherichia coli β-galactosidase (∼465 kDa) at 3.2 Å resolution solved using the GIF Quantum LS energy filter that includes a K2 Summit camera. The first atomic model derived using single-particle cryo-EM analysis closely matches the 1.7 Å crystal structure with a global rmsd of ∼0.66 Å.
