High resolution structure determination by electron cryo-microscopy (cryoEM) and Single Particle Analysis (SPA) has progressed to the point where structures can be determined routinely to better than 2Å on a 300 kV microscope. Here, we show results from Kato et al. at1 Osaka University from the JEOL CRYO ARM™ 300 installed at SPring8 (Riken, Japan), that was obtained on mouse heavy chain apo-ferritin at 1.5Å resolution. The 3D map shows surprising details in the map reflecting the high resolution quality of the data.
