Fig. 4. Stau2 is found in the somatodendritic compartment of neurons and colocalizes with tubulin in dendrites. (A) Hippocampal neurons in culture were fixed and labeled with rabbit polyclonal anti-Stau2. Inset: high magnification of Stau2 in dendrites. (B) Hippocampal neurons in culture were fixed and labeled with rabbit anti-Stau2 (red) or mouse monoclonal anti-tubulin (green) antibodies. The lower panel represents the superposition of both red and green signals. The average diameter of the cell body of a typical CA1 pyramidal neuron is between 8 and 12 µm.
