Our Abpromise guarantee covers the use of ab237995 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
Protein Array Use at an assay dependent concentration.
IHC-P Use a concentration of 1 - 2 µg/ml.

Primary incubation for 30 minutes at room temperature.

Staining of formalin-fixed tissues requires boiling tissue sections in 10mM citrate buffer, pH 6.0, for 10-20 minutes followed by cooling at RT for 20 minutes.

WB Use a concentration of 0.5 - 1 µg/ml. Predicted molecular weight: 66 kDa.


  • Function

    Nuclear 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 similarities

    Belongs to the nuclear hormone receptor family. NR3 subfamily.
    Contains 1 nuclear receptor DNA-binding domain.
  • Domain

    Composed of three domains: a modulating N-terminal domain, a DNA-binding domain and a C-terminal ligand-binding domain.
  • Post-translational

    Phosphorylated 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 localization

    Nucleus. Cytoplasm. Cell membrane. A minor fraction is associated with the inner membrane and Nucleus. Cytoplasm. Cell membrane. Associated with the inner membrane via palmitoylation.

  • Formalin-fixed, paraffin-embedded human Breast Carcinoma tissue stained for Estrogen Receptor using ab237995 at 2 µg/mL in immunohistochemical analysis.

  • Formalin-fixed, paraffin-embedded human Endometrial Carcinoma tissue stained for Estrogen Receptor using ab237995 at 2 µg/mL in immunohistochemical analysis.

  • ab237995 was tested in protein array against over 19000 different full-length human proteins.
    Z- and S- Score: The Z-score represents the strength of a signal that a monoclonal antibody (MAb) (in combination with a fluorescently-tagged anti-IgG secondary antibody) produces when binding to a particular protein on the HuProtTM array. Z-scores are described in units of standard deviations (SD's) above the mean value of all signals generated on that array. If targets on HuProtTM are arranged in descending order of the Z-score, the S-score is the difference (also in units of SD's) between the Z-score. S-score therefore represents the relative target specificity of a MAb to its intended target.
    A MAb is specific to its intended target if the MAb has an S-score of at least 2.5. For example, if a MAb binds to protein X with a Z-score of 43 and to protein Y with a Z-score of 14, then the S-score for the binding of that MAb to protein X is equal to 29.
