Invitrogen™ Estrogen Receptor alpha Monoclonal Antibody (SP1)

Rabbit Monoclonal Antibody

Supplier:  Invitrogen™ MA514501

Catalog No. PIMA514501

Description

This antibody strongly stains the nucleus of epithelial cells in breast carcinomas. It reacts with ER alpha, 67 kDa. No special pretreatment is required for IHC staining.

Estrogen Receptors (ER) are members of the steroid/thyroid hormone receptor superfamily of nuclear receptors. The estrogen receptor is a ligand-activated transcription factor, that when bound to estrogen hormone, induces a conformational change that allows dimerization and binding to estrogen response elements (ERE) in DNA. When bound to EREs, ER can positively or negatively regulate gene transcription through the recruitment of coactivator or corepressor proteins. There are two different forms of the estrogen receptor, alpha and beta, encoded by separate genes (ESR1 and ESR2, respectively). Due to alternative RNA splicing, at least 4 estrogen receptor-alpha isoforms are known to exist (Isoform 1 (66 kDa), Isoform 2 (53 kDa), Isoform 3 (47 kDa), Isoform 4 (35 kDa)). Estrogen receptors are widely expressed in different tissue types and are essential for sexual development and reproductive function. They also play a role in other tissues such as bone. Estrogen receptors are involved in pathological processes including breast cancer, endometrial cancer, and osteoporosis.
