Identification of androgen receptor protein in the nuclei of retinal pigment epithelial cells. The cells were obtained from a 71 year old man following a cardiac arrest and were cultured until utilisation in this immunoperoxidase study. For analysis, cultured cells were cytocentrifuged onto poly-L-lysine coated glass slides (105 cells/slide), fixed in acetone for 5 minutes at 4°C, and then processed for receptor staining. To confirm the specificity of the first antibody staining (A), an aliquot of the rabbit anti-human androgen receptor was preincubated with an excess amount of peptide "AR1-21" (B).
