Image Sample Data

OneView can detect many faint diffraction spots, but the counted data from Metro provides sharper detail and less background noise, allowing you to more accurately characterize crystals and defect structures even at very low electron doses. Here faint spots from a Zeolite diffraction pattern are compared. The TEM settings were not altered when the cameras were switched. 

Low dose imaging of a beam-sensitive Zeolite sample. Detail is observed out to the Nyquist frequency of the camera, even at a dose rate of 0.74 e^-/Å_²/s and a total dose of just 25 e^-/Å_², allowing a large field of view to be imaged. This is made possible by electron counting. 

When combined with Latitude software, Alpine™ delivers high-quality data at the highest imaging throughputs from 100 – 200 keV.

Aldolase (100 kDa) resolved to 3.07 Å at 100 keV acquired with an Alpine™ camera on a Talos F200C (equipped with an SFEG) at 45kx (0.851 Å/pixel) using CDS at ~5.2 e-/pixel/s, 100 ms frames, 10 frames/s. Samples were prepared by manual plunging samples onto glow discharged Quantifoil UltrAuFoil grids with 1.2 μm holes spaced 1.3 μm apart. The study used a Gatan model 626 side-entry holder for all samples and Leginon for data acquisition. Data courtesy Gabe Lander, The Scripps Research Institute.

Preliminary results show remdesivir reduces recovery time for patients who receive the drug. The structure, solved by cryo-EM using Gatan equipment, shows how remdesivir blocks virus replication.

The “spike” protein is the key target for vaccine and drug development efforts. "The K3 camera not only gave us great images…, it also prevented data collection from becoming a bottleneck, ultimately letting our team concentrate on getting the structure as quickly as possible” – UT Austin Lead Scientist
