β-galactosidase expression in the brain of the CAG-loxP.EGFP Cre reporter line 13. (A) X-Gal staining of sagittal brain sections demonstrates widespread β-galactosidase expression throughout the brain. (B,C) Neuronal β-galactosidase expression is demonstrated by co-localization of the neuronal marker NeuN and nuclear localized β-galactosidase in the cortex (B) and CA1 region of the hippocampus (C). Scale bar: 50 μm.
