Figure 4From: Optimization of AAV expression cassettes to improve packaging capacity and transgene expression in neuronsTransgene expression in the mouse brains with CW3SL expression cassette. Either CWB-EGFP (A) or CW3SL-EGFP (B) was injected together with CWB-tdTomato into the hippocampal CA1 region. The expression levels of EGFP and tdTomato were detected by confocal fluorescence imaging. Scale bar, 200 μm.Back to article page
