Target

  • 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
    modifications
    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.

Images

  • ab16660 staining Estrogen Receptor alpha in MCF7 cells. The cells were fixed with 4% formaldehyde (10min), permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated overnight at +4°C with ab16660 at 1/250 dilution (shown in green) and ab195889, Mouse monoclonal [DM1A] to alpha Tubulin (Alexa Fluor® 594), at 2µg/ml (shown in red). Nuclear DNA was labelled with DAPI (shown in blue).
    Image was taken with a confocal microscope (Leica-Microsystems, TCS SP8).

  • IHC image of ab16660 staining Estrogen Receptor alpha in normal human cervix formalin-fixed paraffin-embedded tissue sections*, performed on a Leica Bond. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab16660, 1/250 dilution, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX. No primary antibody was used in the negative control (shown on the inset).

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

Question
Answer

Thank you for your telephone enquiry this morning.


As discussed on the telephone, I can confirm these antibodies are different and will be detecting different eptiopes. They have also been tested ina slightly different list of applications and species.One other major difference is that ab16660is sold as tissue culture supernatant, ab27614 is purified.

During our discussions, you mentioned these may be used for diagnostics. Please notethat regrettablyour products are not accredited for clinical diagnostic use.However, we canprovide our 6 month guarantee for the applications and species listed on the individual datasheets.

We do sell a large range of IHC reagents now which I hope will be helpful to you. They can be found by searching on our website, or you may find it helpful to click on the links from the following IHC reagentspage:
