Characterization of the EELSs by Electron microscopy. (A) Wild-type and (B–F) COG KO HEK293T cells grown on sapphire disks were high pressure frozen, fixed, embedded in Araldite 502/Embed 812 resin and analyzed by transmission electron microscopy. Note that the EELSs (labeled with star) are very prominent vacuole-like compartments in every COG KO cell.
