1. Unaligned multi-frame micrographs of SSU processome assembly intermediates - Dataset1 Kre33 pulldown
Category:
micrographs - multiframe
Image format:
TIFF
No. of images or tilt series:
44272
Image size:
(11520, 8184)
Pixel type:
UNSIGNED BYTE
Pixel spacing:
(0.54, 0.54)
Details:
The dataset was collected on a Titan Krios electron microscope operating at 300 kV equipped with an energy filter (slit width 20 eV), a Cs corrector and a K3 Summit detector set in super-resolution mode. Unaligned multi-frame micrographs were recorded at a nominal magnification of 64,000× with a pixel size of 0.54 Å/pixel, a defocus range of -1 to -2.5 µm, and a total dose of 60.0 e-/Å2 (40 frames). The gain reference was applied on-the-fly during data collection.
