Western immunoblots showing clear atypical scrapie profiles in sheep in the following brain regions; brainstem of donor ARRa (lane 7), frontal cortex of donor ARRb (lane 8) and frontal cortex of donor AHQ (lane 19). The hippocampus and basal nuclei of recipient animal 11 (lanes 15 and 16, respectively) and cerebellum of recipient animal 12 (lane 18). No discernible signal was seen in the medulla of donor ARRb (lane 9), and only a faint profile was visible for the obex of recipient animal 12 (lan
