Immunoelectron microscopic localization of estrogen receptor with monoclonal estrophilin antibodiesMF Press, NA Nousek-Goebl and GL Greene
The recent production of a series of monoclonal estrophilin (estrogen receptor) antibodies recognizing estrogen receptor derived from a wide variety of animals and target tissues permits the development of immunoelectron microscopic techniques for identifying estrogen receptor. We have determined suitable conditions for the ultrastructural localization of estrogen receptor in tissue sections. Localization of receptor was observed in the euchromatin, but not in the marginated heterochromatin or nucleoli of epithelial and stromal nuclei of human endometrium. Competition studies indicate that only estrogen receptor specifically inhibits nuclear staining. The absence of any specific cytoplasmic localization at the electron-microscopic level is consistent with earlier light-microscopic observations and suggests that the majority of the cellular pool of estrophilin exists in the nucleus of hormone-responsive cells.
