Figure 3. Syntaxin 3B in photoreceptor terminals partially colocalizes with ribeye.
Retinal sections where double labeled with antibodies against syntaxin 3 and ribeye/CTBP2 or the synaptic vesicle marker SV2. Synaptic terminals are marked with asterisks. Some syntaxin 3B is colocalized with ribeye but a large fraction occupies ribeye free parts of the plasma membrane. Scale bar = 5 μm.
