Fig. 9From: Immunogold labeling of synaptic vesicle proteins in developing hippocampal neuronsDense core vesicles (DCV, arrows) sometimes exist in groups in young axons at 3 (c), 4 (a, b) and 6 (d) DIV. The vesicular membranes of DCV label for SV2 (a) and synaptotagmin (b), but not for synaptophysin (c). Label for Piccolo, an AZ cytomatrix protein is located on the outside of the DCV (d).
