AKAP150 co-distributes with Robo2 and Robo3 in the adult brain. Sagittal paraffin-embedded sections from 16-week-old mouse brains were immunostained for AKAP150 (A–C, E–G, I–K, and M–O; red) and either Robo2 (A, B, D, I, J, and L; green)) or Robo3 (E, F, H, M, N, and O; green). A–H, staining in the CA1 region of the hippocampus. I–P, staining of the islands of Calleja in the olfactory tubercle. Images from the top panel were collected at low magnification, whereas the bottom panels represent high magnification confocal images from the same region.
