Figure 1. Developmental expression of phosducin protein in the embryonic and postnatal retina. Immunohistochemical staining was performed on coronal sections starting at (A) E10.5 (before cone birth) through (I) P21. Anti-phosducin antibody labeled photoreceptors starting at E12.5 (arrows in C) and continued through all time points tested. Arrowhead indicates the RPE. Scale bars = 100 µm.
