Immunohistochemical staining with 39-7-7 antibody, which was generated and specifically reacted with a the C-terminal part of B120 protein, in human developing brain (A) and intact adrenal medulla (B). Immunohistochemical staining of developing precentral gyrus of cerebrum at 17 weeks, the neuroprogenitor cells in the germinal zone at subventricular area (sub) was stained by 39-7-7. Migrating neural cells in the intermediate layer (int) were not stained by 39-7-7 antibody. The pericytoplasmic region in pheochromocytes in intact adrenal gland medulla was also stained, but not as strongly by 39-7-7 antibody. Original magnifications: ×100 (A), ×400 (B).
