Fig 7

(a) Numerous vesicles (arrows) of various sizes are HRP-positive in a young cultured hippocampal neuron. At some locations eHRPsyt1 can be found at the plasma membrane (arrowhead). Bar = 200 nm. (b) An electron micrograph of an eHRPsyt1-positive presynaptic bouton. Note the numerous synaptic vesicles distributed throughout the synaptic vesicle cluster. Some labeled synaptic vesicles are also docked at the active zone (to the left). Bar = 200 nm.
