Estrogen Receptor Alpha antibody | 6F11
The detection of estrogen (ER) and progesterone (PR) receptors using immunohistochemical staining of formalin fixed, paraffin embedded (FFPE) tissue, has gradually replaced ligand binding assays, to become the most common method for the determination of the ER/PR status of breast tumors (Yaziji et al. 2008). Approximately 75% to 80% of breast tumors have estrogen and/or progesterone receptors, and the presence of these receptors helps determine both the patients prognosis and the effectiveness of hormonal therapy (Bhargava et al. 2012).
Mouse anti human estrogen alpha antibody, clone 6F11 has been used successfully for identification of ERα on breast cancer cell lysates using Western blotting and for the immunohistochemical detection of ERα in breast cancer tissues (Ambroise et al. 2011).
