TEM of 20S Proteasomes
Transmission electron micrograph (TEM) of 20S proteasomes from the halophilic archaeon Haloferax volcanii. Typical four-stacked rings are visible in the side-on views. The central channel is visible in the end-on views. The particles were negatively stained with uranyl acetate. Bar, 100 nm.
Thanks to Dr. Henry C. Aldrich and Donna Williams for assistance with the
transmission electron micrograph.
