Immunofluorescent analysis of Estrogen Receptor beta (ER-beta, green) in HeLa cells. Formalin fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 10 minutes at room temperature and blocked with 5% normal goat serum (Product # 31873) for 15 minutes at room temperature. Cells were probed with an ER-beta polyclonal antibody (Product # PA1-312) at a dilution of 1:100 for at least 1 hour at room temperature. Cells were then washed with PBS and incubated with DyLight 488 goat anti-rabbit IgG secondary antibody (Product # 35552) at a dilution of 1:200 for 30 minutes at room temperature. Nuclei (blue) were stained with Hoechst 33342 dye (Product # 62249). Images were taken on a Thermo Scientific ArrayScan at 20X magnification.

PA1-312 detects estrogen receptor (ER) beta from rat, human, and mouse samples.
PA1-312 has been successfully used in Western blot, immunofluorescence, and immunohistochemistry procedures. By Western blot, this antibody detects an ~55 kDa protein representing ER beta from rat brain homogenate. Immunohistochemical staining of ER beta in rat cerebellum with PA1-312 results in staining of cells in the paraventricular nucleus and retrochiasmatic nucleus.
The PA1-312 immunogen is a synthetic peptide corresponding to residues C(467) C S T E D S K N K E G S Q N L Q S Q(485) of mouse ER beta.
Recombinant ER beta expressed in baculovirus system (Cat. # RP-311 and RP-312) can be purchased for control experiments in Western blot and gel shift assays.
The human ER-beta is a newly discovered estrogen receptor initially cloned and characterized from testis. The size and structure of ER-beta is very similar to ER-alpha with the ligand and DNA binding domains being highly conserved, while the amino terminus which serves as their transactivation domain has diverged significantly. Similar in function to ER-alpha ER-beta binds to estrogen with a high affinity and regulates estrogen specific gene activation through direct interaction with estrogen response elements (ERE's).
