Confocal microscope images of adult rat cerebellum, showing the distribution of GAD67 (immunolabeled with rhodamine: red) and Reelin mRNA (detected with biotinylated oligoprobe base pairs 1264–1311 and immunolabeled with fluorescein: green). Confocal microscope images of adult rat cerebellum, showing the distribution of GAD67 (immunolabeled with rhodamine: red) and Reelin mRNA (detected with biotinylated oligoprobe base pairs 1264–1311 and immunolabeled with fluorescein: green). Note that GAD67 is found predominantly in the Purkinje cell layer (Left), whereas mRNA for Reelin is found primarily in the granule cell layer (Right). C. Pesold et al.
