Fig. 4. Syntaxin 1 is present at the active zone of the presynaptic terminal.

Fig. 4

(A) is from dissociated hippocampal cultures labeled for syntaxin 1A, and (B) is from CA1 region of hippocampus from perfusion-fixed mouse labeled for syntaxin 1 (ab2). Label for both antibodies were present on the plasma membrane of axons, but not dendrites (den) or peri-synaptic astrocytes (astro). Small arrows point to label at the active zone, which apposes the postsynaptic density, the area between two large arrows.
