Rapid-freeze EM images of spherical aggregates in [PSI+] and G74-D694 [PSI+] cells. (A–F) Rapid-freezing EM images of spherical aggregates in [PSI+] (A–D) and G74-D694 [PSI+] (E and F) cells. The cells contain laterally aligned fibrils (A), less-ordered, amorphously bundled fibrils (B and C), a mixture of the less-ordered and laterally aligned fibrils (D), and assemblies of well-ordered, laterally aligned fibrils (E and F). (G–I) Immunogold labeling of the thin-section EM images of aggregates in G74-D694 [PSI+] cells. An anti-GFP antibody was used to attach the gold. (A–I) The boxed areas in the left images are magnified on the right.
