(a) Cryo-EM image of ice-embedded sodium channels extracted from the electric organ of the electric eel, Electrophorus electricus electroplax. Channel proteins are marked by white squares. (b) Micrograph of negatively stained sodium channels. As demonstrated by arrowheads, particles are of uniform size but different shapes. This indicates attachment to the grid surface at various angles. The scale bars represent 200 Å. |
