Electron microscopy of the Na+-NQR complex stained with 1% uranyl acetate. (a) Micrographs of GraFix-pretreated Na+-NQR complexes show uniform particles with a diameter of 100-150 Å. (b) Characteristic two-dimensional class averages of the complex reveal asymmetric particles consisting of multiple domains. The scale bars are 500 Å in the overview and 50 Å for the two-dimensional class averages.  [article HTML]
