Supplementary Figure 4: The fluorescence of the reporter gene can be enhanced by immunostaining with a specific antibody.

(a) Confocal image of EGFP fluorescence in a coronal section of a mouse neocortex at P7 after in utero transfection (at E15.5) in an experiment that resulted in low transfection efficiency. (b) Confocal image of the same slice after immunostaining with anti-GFP antibody (Abcam, cat. no. Ab13970; concentration 1:1000). Images in (a) and (b) were acquired using a confocal microscope with the same parameters. Scale bar: 100 µm.
