Distribution of nanogold-labeled AChE sites in the synaptic cleft of the mouse endplate. (A,B) Electron micrographs of cross sections through endplates of mouse sternomastoid muscles that had been incubated with Fas-biotin followed by 1.4 nm-nanogold-streptavidin and light silver intensification (details under “Materials and Methods” section). Gold particles (black) are seen over the PC (A, arrowheads) and PJFs, and are predominantly associated with the basal lamina (BL; B, hollow arrows). Bars, 0.2 μm.
