Immunohistochemical staining of P45017α in the hippocampal formation of an adult male rat. (A) The coronal section of the whole hippocampal formation. (B) The CA1 region. (C) The CA1 stained with anti-P45017α IgG preadsorbed with purified P45017α. (D) Fluorescence dual staining of P45017α (green) and neuronal nuclear antigen (red). (E) Fluorescence dual staining of P45017α (green) and glial fibrillary acidic protein (red). (F) Fluorescence dual staining of P45017α (green) and myelin basic protein (red). In D–F, superimposed regions of green and red fluorescence are represented by yellow. so, stratum oriens; pcl, pyramidal cell layer; sr, stratum radiatum. (Scale bar, 800 μm for A and 120 μm for B–F.)
