UF-stained apoferritin particles feature an electron-dense core, while SPT- or AMo-stained particles do not. Representative raw micrographs of apoferritin stained with (a) UF, (b) SPT or (c) AMo. Scale bars are 100 nm. The insets show the boxed area at 2.5× magnification. For micrographs of SPT and AMo staining without prior on-grid fixation, see Supplementary Fig. S7. For a quantification of particles according to their core area, see Supplementary Fig. S6. |
