Anti-ERα Antibody

The Estrogen Receptor alpha (ERα) is a ligand-activated nuclear receptor transcription factor central to estrogen-driven gene regulation in reproductive, skeletal, cardiovascular, and neural tissues. This unconjugated rabbit polyclonal reagent recognizes ERα and is validated for western blot, immunohistochemistry, and ELISA workflows on human and mouse samples. Supplied in a 100 µl vial, the antibody supports breast cancer, endometrial, ovarian, and reproductive biology studies investigating hormone response, tumor classification, and steroid receptor signaling pathways. Store refrigerated; aliquot to limit repeated freeze-thaw cycles. Each lot is affinity-purified and quality-controlled for research use only, providing reliable detection of the full-length receptor and its splice variants in cell lysates, tissue sections, and prepared protein samples. Antibodies.com offers this primary antibody as part of its broader catalog of nuclear receptor and cancer research reagents.
