Abstract Rat, human, and mouse tissues were stained immunohistochemically using mono- and polyclonal androgen receptor antibodies. Monoclonal antibodies were raised in rats and used to stain human and mouse tissues; polyclonal antibodies were raised in rabbits and used to stain rat tissues. Frozen tissue sections were incubated with the appropriate androgen receptor antibody and staining was completed by the indirect avidin-biotin peroxidase method. A comprehensive survey of rat and mouse tissues was performed. Antibody staining was found exclusively in the nucleus of certain specific cell types, suggesting that the androgen receptor is a nuclear protein. All male sexual organs in the rat showed strong positive nuclear staining for androgen receptor. Weaker positive reactions were seen in kidney, liver, adrenal cortex and pituitary gland. Furthermore, positive staining for androgen receptor was exhibited in skeletal, cardiac and smooth muscle cells, and central nervous tissue. Female reproductive organs also contained androgen receptor-positive cells. The spleen was found to be the only organ examined which did not stain for androgen receptor. The monoclonal antibody could also demonstrate androgen receptor-positive cells in a human prostatic cancer and in a prostate with benign hyperplasia. These data demonstrate the use of antibodies in revealing cellular/subcellular distribution of androgen receptor in target tissues.
