Immunofluorescent localization of the estrogen receptor using antibodies AER314 and AER311 in cyrostat cross-sections of endometrium obtained on day 16 of the estrous cycle after uterine infusion with a BSA-saline control solution (A-B), interferon-tau (C-D), ICI 182, 780 (E-F) or estrogen (G-H). A tissue section treated with mouse IgG in place of primary antibody is shown inset in A. Specific nuclear reactivity was present in some cells of the stroma (arrows) in control animals. LE – luminal epithelium, S – stroma, GE – glandular epithelium. Magnification for A-C was 400X, D,F,H was 200X and E,G 100X.
