Immunofluorescent analysis of Aryl Hydrocarbon Receptor using Aryl Hydrocarbon Receptor Monoclonal Antibody (RPT9) (Product# MA1-513 ) shows staining in A2058 Cells. Aryl Hydrocarbon Receptor (green), F-Actin staining with Phalloidin (red) and nuclei with DAPI (blue) is shown. Cells were grown on chamber slides and fixed with formaldehyde prior to staining. Cells were probed without (control) or with an antibody recognizing Aryl Hydrocarbon Receptor (Product# MA1-513 ) at a dilution of 1:20 over night at 4 °C, washed with PBS and incubated with a DyLight-488 conjugated secondary antibody (Product# 35552 for GAR, Product# 35503 for GAM). Images were taken at 60X magnification.

MA1-513 detects the aryl hydrocarbon receptor (AhR) from human, mouse, and rat cells.
MA1-513 has been successfully used in immunoprecipitation, chromatin immunoprecipitation, immunocytochemistry, immunohistochemistry, immunofluorescence, and gel shift procedures. This antibody specifically immunoprecipitates a single ~95 kDa protein representing AhR from Hepa 1 cytosol. Although MA1-513 can be used in Western blotting procedures, MA1-514 (clone RPT1) is recommended for this procedure.
The MA1-513 immunogen is a synthetic peptide corresponding to residues R(12) K R R K P(17) V(22) K P I P A E G I K(31) of mouse AhR.
The aryl hydrocarbon receptor (AhR), also known as the dioxin receptor, is a ligand-activated helix/loop/helix transcription factor found in a variety of vertebrate species. The known ligands for AhR are foreign planar aromatic compounds, such as polycyclic aromatic compounds and halogenated aromatic compounds such as 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). Unlike the steroid/thyroid hormone receptors, there is no known physiological ligand for the Ah Receptor.
Studies indicate that in non-ligand activated cells, AhR is found complexed with HSP90 predominantly in the cytoplasm. Upon binding to an agonist, the ligand-activated AhR is believed to transform to a nuclear, DNA binding form. This transformation process appears to involve dissociation of HSP90 from AhR followed by formation of a heterodimer with AhR nuclear translocator protein (Arnt). The AhR-ligand complex appears to initiate gene transcription of cytochrome P450 1A1.
