Immunofluorescent analysis of Aryl Hydrocarbon Receptor in NIH-3T3 cells. Cells were grown on chamber slides and fixed with formaldehyde prior to staining. Cells were probed without (control) or with a Aryl Hydrocarbon Receptor monoclonal antibody (Product # MA1-514) at a dilution of 1:200 overnight at 4 C, washed with PBS and incubated with a DyLight-488 conjugated secondary antibody (Product # 35503). Aryl Hydrocarbon Receptor staining (green), F-Actin staining with Phalloidin (red) and nuclei with DAPI (blue) is shown. Images were taken at 60X magnification.

MA1-514 detects the aryl hydrocarbon receptor (AhR) from human, mouse, and rat cells.
MA1-514 has been successfully used in Western blotting, immunoprecipitation, immunofluorescence and immunohistochemistry procedures. By Western blot, this antibody detects an ~96 kDa protein representing AhR, with some minor non-specific bands observed in certain samples.
MA1-514 immunogen is residues 12-31 from the human AhR protein with amino acids 18-21 being omitted.
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.
