Immunohistochemical localization of adrenocorticotropin and melanocyte stimulating hormone in pars intermedia of rat hypophysis

The sites of production of adrenocorticotropin (ACTH) and melanocyte stimulating hormone (MSH) are studied by the immunoglobulin-peroxidase bridge technique, using antisera prepared against synthetic porcine β 1–24 and β 17–39 ACTH, and bovine β MSH on the rat adenohypophysis. Presence of ACTH all over the pars intermedia (PI) is indicated by staining with… (More)
