Gallery of transmission electron micrographs of ribosomes purified from a rat liver homogenate by sucrose gradient centrifugation, and negatively stained with uranyl acetate. The 3 columns at left illustrate lateral views with arrows denoting the junctions between large and small subunits. The 4 columns at right illustrate 'frontal' views, with the notch demarcating the junctions between large and small subunits.
Samples were placed on carbon coated collodion films, negatively stained with aqueous uranyl acetate, and examined with a Philips 300 TEM. See also Plate IX in: N. Yoshiaki et al. 1971. Structure of liver ribosomes studied by negative staining. J Mol Biol 60:303-323
