The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||1/500 - 1/1000. Detects a band of approximately 66 kDa (predicted molecular weight: 68 kDa).|
|IHC-P||1/500 - 1/1000. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.|
FunctionNuclear hormone receptor. The steroid hormones and their receptors are involved in the regulation of eukaryotic gene expression and affect cellular proliferation and differentiation in target tissues. Can activate the transcriptional activity of TFF1.
Sequence similaritiesBelongs to the nuclear hormone receptor family. NR3 subfamily.
Contains 1 nuclear receptor DNA-binding domain.
DomainComposed of three domains: a modulating N-terminal domain, a DNA-binding domain and a C-terminal ligand-binding domain.
modificationsPhosphorylated by cyclin A/CDK2. Phosphorylation probably enhances transcriptional activity.
Glycosylated; contains N-acetylglucosamine, probably O-linked.
Ubiquitinated. Deubiquitinated by OTUB1.
Dimethylated by PRMT1 at Arg-260. The methylation may favor cytoplasmic localization.
Palmitoylated (isoform 3). Not biotinylated (isoform 3).
Cellular localizationNucleus. Cytoplasm. Cell membrane. A minor fraction is associated with the inner membrane and Nucleus. Cytoplasm. Cell membrane. Associated with the inner membrane via palmitoylation.

ab79413, at 1/500 dilution, staining Estrogen Receptor alpha in paraffin-embedded human breast carcinoma tissue by Immunohistochemistry.
Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
ab79413 staining Estrogen Receptor alpha in Baboon placenta and fetal ovary tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with formaldehyde and blocked with 5% serum for 30 minutes at 22°C; antigen retrieval was by heat mediation in 10mM sodium citrate, pH 6.0. Samples were incubated with primary antibody (1/500 in PBS + 5% normal goat serum) for 16 hours at 4°C. A Biotin-conjugated goat anti-rabbit IgG polyclonal (7µg/ml) was used as the secondary antibody.
