Figure 5. Expression of the ERK2 protein kinase

Cryosections of retinas from three postnatal ages are shown. Panels A, B, and C show sections immunofluorescently stained for ERK2. Panels D, E, and F show DAPI staining images of the same sections shown in A, C, and E, respectively. Panels G, H, and I show sections stained for secondary antibody alone; panels J, K, and L show their corresponding DAPI images. The scale bar in panel F represents 100 μm for all panels. The meanings of the abbreviations referred to in this figure are: gcl (ganglion cell layer), inl (inner nuclear layer), ipl (inner plexiform layer), is (inner segment), onl (outer nuclear layer), opl (outer plexiform layer), os (outer segment), rpe (retinal pigmented epithelium), vz (ventricular zone).
