Figure 3. Retinal cross sections were stained for normal depolarizing bipolar cell function using an antibody against protein kinase
C alpha (PKCα; green) and with a cell body label (blue). Depolarizing bipolar cells (DBCs) are present in the tg21 no b-wave
(nob) retina (right), with a distribution that is comparable to that of non-transgenic (left) littermates.
