Protein Name & Synonyms:
Estrogen Receptor alpha
Immunohistology - Frozen, Immunohistology - Paraffin
This antibody recognizes the human estrogen receptor alpha chain. .
The detection of estrogen (ER) and progesterone (PR) receptors using immunohistochemical staining of formal fixed paraffin embedded (FFPE) tissue, has gradually replaced ligand binding assays (LBA), to become the most common method for the determination of the ER/PR status of breast tumors. Approximately 75% to 80% of breast tumors have estrogen and/or progesterone receptors, and the presence of these receptors helps determine both the patient's prognosis and the effectiveness of hormonal therapy
