Figure 2. Percentage of phosphodiesterase
adjacent to the rod outer segment plasma membrane measured with two
different phosphodiesterase (PDE) antibodies. Retinal sections were
processed for immunogold labeling using PDEα and PDEγ antibodies,
respectively. Distribution profiles of PDE in light- and dark-adapted
retinas were analyzed with each antibody. The percentage of total PDE
immediately adjacent to the plasma membrane (within 25 nm) was plotted.
The asterisk indicates a p≤0.002.
