During hippocampal neuron development in vitro, N-cadherin becomes selectively localized to excitatory synapses. This image shows synapses that are also immunopositive for the presynaptic glutamate transporters V-glut 1 and 2. Corresponding images in this image group show immunolocalization of N-cadherin, and the postsynaptic NMDA receptor.
Individual fluorescent images were acquired using a Nikon Diaphot 300 with a 60X objective. Preparation was fixed in 4% paraformaldehyde and permeabilized with .01% TritonX-100.
