Immunofluorescent analysis of Estrogen Receptor alpha using Anti-Estrogen Receptor alpha Monoclonal Antibody (EVG F9) (Product# MA3-310) shows staining in MCF-7 Cells. Estrogen Receptor alpha staining (green), F-Actin staining with Phalloidin (red) and nuclei with DAPI (blue) is shown. Cells were grown on chamber slides and fixed with formaldehyde prior to staining. Cells were probed without (control) or with or an antibody recognizing Estrogen Receptor alpha (Product# MA3-310) at a dilution of 1:200 over night at 4 °C, washed with PBS and incubated with a DyLight-488 conjugated secondary antibody (Product# 35503, Goat Anti-Mouse). Images were taken at 60X magnification.

MA3-310 detects estrogen receptor alpha in human and rabbit samples.
MA3-310 has been successfully used in immunohistochemistry, immunoprecipitation and Western blot procedures. By Western blot, this antibody detects a ~68 kDa protein representing estrogen receptor alpha in MCF-7 cells, human breast tumors, and rabbit vaginal tissue. In immunohistochemistry this antibody recognizes the estrogen receptor alpha in MCF-7 cells, human breast tissue, and human smooth muscle cells.
The MA3-310 immunogen is a mix of synthetic peptides corresponding to residuesT(140) V R E A G P P A F Y R P N S(154) & E(247) V G M M K G G I R K D R R G G R(263) of human ER alpha.
The Estrogen Receptor (ER) is a 67 kDa protein and a member of the steroid family of nuclear receptors. ER is a ligand-activated transcription factor and, when bound to estrogen hormone, induces a conformational change that allows dimerization and binding to estrogen response elements (ERE) sequences. When bound to DNA, ER can positively or negatively regulate gene transcription through the recruitment of coactivator (e.g. SRC-1) or corepressor (e.g. NCoR) proteins.
