Details:
Raw unaligned movie files (tif format, 79 frames, not gain corrected), and gain correction image (mrc format).
Cryo-EM imaging of the β2AR-Gs(GTP) complex was performed on a Titan Krios electron microscope operated at 300 kV accelerating voltage, and equipped with a K3 Summit direct electron detector and post column energy filter. Super-resolution pixel size: 0.43385Å. Μovies were obtained at an exposure rate of 32.46 electrons/Å^2/sec. The total exposure time was 1.999 sec over 79 frames per movie stack.
