Immunohistochemistry (Formalin-fixed paraffin-embedded sections) analysis of human breast invasive ductal carcinoma with ESR1 monoclonal antibody, clone ER506 (Cat # xxxx) at 1:25 using peroxidase-conjugate and DAB chromogen.
Flow cytometric analysis of MCF-7 cells using ESR1 monoclonal antibody, clone ER506 (Cat # MAB11317) at 1 ug/106 cells. Paraformaldehyde and 0.1% Tween-PBS were used to fix and permeabilize the cells.
This gene encodes an estrogen receptor, a ligand-activated transcription factor composed of several domains important for hormone binding, DNA binding, and activation of transcription. The protein localizes to the nucleus where it may form a homodimer or a heterodimer with estrogen receptor 2. Estrogen and its receptors are essential for sexual development and reproductive function, but also play a role in other tissues such as bone. Estrogen receptors are also involved in pathological processes including breast cancer, endometrial cancer, and osteoporosis. Alternative splicing results in several transcript variants, which differ in their 5' UTRs and use different promoters. [provided by RefSeq
