General description

Estrogen Receptor alpha is a 65 kDa protein and a member of the steroid family of nuclear receptors. Estrogen Receptor alpha is a ligand-activated transcription factor that, when bound to estrogen, induces a conformational change that allows dimerization and binding to estrogen response element sequences. When bound to DNA, Estrogen Receptor alpha can positively or negatively regulate gene transcription. Like other steroid hormone receptors, Estrogen Receptors are intracellular proteins. Estrogen Receptors play an important role in regulating mammary gland growth and differentiation. Breast tumors that are ER positive may also show a more favorable response to anti-estrogen therapies.

Specificity

This antibody recognizes the C-terminus of Estrogen Receptor alpha.

Immunogen

Epitope: C-terminus.
KLH-conjugated linear peptide corresponding to the C-terminus of rat Estrogen Receptor alpha.

Application

  • Tested applications
  • Immunohistochemistry (Paraffin) Analysis: A 1:400 dilution from a representative lot detected Estrogen Receptor in human stomach, human uterine cancer, human breast cancer and human cervical cancer tissue sections.
  • Immunoprecipitation Analysis: 4 µg from a representative lot immunoprecipitated Estrogen Receptor in MCF-7 cell lysate.
  • Immunocytochemistry Analysis: A 1:500 dilution from a representative lot detected Estrogen Receptor in MCF-7 cells.
  • Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user. "
Anti-Estrogen Receptor , Cat. No. 06-935, is a rabbit polyclonal antibody that detects Estrogen Receptor and is tested for use in Western Blotting, Immunocytochemistry, Immunoprecipitation, and Immunohistochemistry (Paraffin).
