Immunofluorescent analysis of Estrogen Receptor Alpha (green) in T47D cells. The cells were fixed with formalin for 15 minutes, permeabilized with 0.1% Triton X-100 in TBS for 10 minutes, and blocked with 3% BSA (Product # 37525) for 30 minutes at room temperature. Cells were stained with or without Estrogen Receptor Alpha monoclonal antibody (Product # MA1-310), at a concentration of 10ug/ml overnight at 4C, and then incubated with a Superclonal goat anti-mouse IgG Alexa Fluor 488 secondary antibody (Product # A28175) at a dilution of 1:1000 for 30 minutes at room temperature (both panels, green). Nuclei (both panels, blue) were stained with Hoechst 33342 dye (Product # 62249). Images were taken on a Thermo Scientific ToxInsight at 20X magnification.

MA1-310 detects both the steroid occupied and unoccupied forms of the estrogen receptor (ER) alpha from human samples. MA1-310 detects ER alpha and does not cross react with ER beta.
MA1-310 has been successfully used in Western blot, immunohistochemistry, immunoprecipitation, gel shift, flow cytometry, and immunocytochemical experiments. By Western blot, this antibody detects an ~66 kDa protein representing ER alpha from MCF-7 cell extract.
The Estrogen Receptor (ER) is a 66 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.
