JEOL Announces New Cold Field Emission Cryo-Electron Microscope: CRYO ARM™ 300 II
JEOL Ltd. (President & COO Izumi Oi) announces the release of a new cold field emission cryo-electron microscope (cryo-EM), the CRYO ARM™ 300 II (JEM-3300), to be released in January 2021. This new cryo-EM has been developed based on the concept of “Quick and easy to operate and get high-contrast and high-resolution images”.
Cryo ARM™ 300II Product Development Background
Recent dramatic improvement of resolution in single particle analysis (SPA) using cryo-EM has led to SPA as an essential method for structural analysis of proteins. To address this market, JEOL released the CRYO ARM™ 300 in 2017. Equipped with a cold field emission gun (Cold FEG) for enhanced resolution and a cryo-stage for loading multiple samples, the CRYO ARM™ 300 has continued to achieve best-in-class resolution for SPA.
JEOL Announces 2020 Microscopy Image Grand Prize Winners
JEOL USA awarded two Grand Prizes to winners of its 2020 Electron Microscopy Image Contest and kicked off its 2021 Image Contest at the beginning of the new year. The annual contest showcases JEOL microscope users’ artistically or esthetically pleasing images with good composition, sharp focus, and technical competency, especially in the use of accelerating voltage.
The Grand Prize Transmission Electron Microscope (TEM) Image award was given to Lita Duraine, a certified electron microscopist at Baylor College of Medicine in Baylor, Texas. “The Screamer 2020” resembles a screaming cartoon character (possibly a good depiction of how many felt about 2020), but is actually a detailed, high magnification image showing firing between boutons in a Drosophila melanogaster (fruit fly) sample. It was imaged on the JEOL JEM-1400Plus TEM as part of a bouton study on muscle weakness.
