Brown Norway rats were intravitreally injected with either rAAV-hsyn-GFP or rAAV-hsyn-Brn3b and maintained for 2 weeks. Following sacrifice, frozen retinal sections were obtained and stained with an antibody against Brn3b (pseudo-green) and Neu N (pseudo-red). An increase in immunoreactive levels of Brn3b was observed in retinal sections obtained from AAV-hsyn-Brn3b injected rats, compared to those injected with AAV-hsyn-GFP (control vector). Co-staining of Brn3b with NeuN was observed in all retinal sections.
