ER Antibody / Estrogen Receptor alpha

Estrogen receptor (ER) is an important regulator of growth and differentiation in the mammary gland. ER presence in breast tumors indicates an increased likelihood of response to anti-estrogen (e.g. tamoxifen) therapy. Clone ER506 antibody strongly stains nuclei of epithelial cells in breast carcinomas.
