Fig. 7. PI4Kß in hippocampal neurons. The distribution of PI4Kb in 15-day-old
neurons was analyzed by confocal fluorescence microscopy. (A) Neurons
immunolabeled with anti-PI4Kß antibodies. (B-D) Superimposed images
(merge) of optical sections collected from neurons doubly immunostained for
PI4Kß (red, B-D) and TGN38 (green, B), PDI (green, C) or synaptobrevin 2
(green, D). Note that immunolabeling for PI4Kß partially overlaps with
that for the Golgi complex marker TGN38 or for the ER marker PDI (B,C). Bars,
10 µm.
