title: Immunocytological localization of estrogen in human mammary carcinoma cells by horseradish--anti-horseradish peroxidase complex.
abstract: Tissues from 25 female and 2 male patients of mammary carcinoma were examined by the horseradish--anti-horseradish peroxidase complex to localize the presence of estrogen. Carcinoma cells of 10 females and 2 male patients showed positive staining by this technique. The nucleus and cytoplasmic membrane showed the reaction. This method is useful in identifying the exact location of the hormones or hormone-like substances in the malignant cells and, perhaps, will be of great help in selecting the patients for management.
