The electron-dense gold particles can be easily identified in the transmission electron microscope and enable the quantitation of the gold label in relation to the compartments of interest. Gold labels appear in TEM images as dark particles –like black dots- against a lighter (less electron-dense) background.

If a positive potential up to 5 kV or a negative potential down to about -0.5 kV was applied to screen Sno significant effect was observed in the orientation of gold particles. On the other hand, if a negative potential less than -1.5 kV was applied to the screen, the fraction of the parallel-orientated particles was appreciably increased.
