(A) Anatomical view of the adrenal gland together with adjacent kidney, pancreas, spleen, stomach and skeletal muscles; B) Weak, diffuse immunoreaction is seen in the adrenal cortex and, less, in the medulla. This is evident when compared to control staining shown in (C); C) Control staining for (B) performed with normal rabbit serum; D) Detail of the contrast between the immunoreaction in the cortex and medulla at higher magnification; E) Adrenal assayed with the negative control (normal rabbit serum); Adr - adrenal gland; Cx - cortex; K - kidney; M - muscle; Me - medulla; NRS - normal rabbit serum; P - pancreas; Spl - spleen; St - stomach.
