Electron microscopy, of particles

Fig. 6. Electron microscopy of particles obtained from different zones of sucrose gradient and fixed with 2 percent formaldehyde. Shadow-cast preparations, X90,000. A. preparation of 308 particles obtained without Inhibitor. B. particles from 45S zone C. from 70S and D. from 90 to 100S zone. Preparations B to D are obtained from the sample isolated in the presence of RNase inhibitor. (From Samarina et al., 1968a. J. Molec. Bio ., 33 251-263.)...
