Product Specific Information

Description: This 4MEJJ monoclonal antibody recognizes mouse aryl hydrocarbon receptor (AHR). The AHR is a ligand-activated transcription factor that mediates the toxic effects of a diverse group of environmental contaminants, most notably aryl hydrocarbons such as polychlorinated biphenyls (PCB) and tetrachlorodibenzo-p-dioxin (TCDD). The AHR has also been shown to bind to a number of naturally occurring compounds found in fruits and vegetables as well as compounds generated through normal cellular metabolism. AHR is localized in the cytoplasm in a complex that includes HSP90, p23, and XAP2/AIP/ARA9. Upon ligand-binding, AHR translocates to the nucleus and binds with aryl hydrocarbon receptor nuclear translocator (ARNT), and this complex binds to the consensus DNA sequence, GCGTG, found in the promoter/enhancer regions of many genes such as CYP1A1. The AHR is expressed in many cell types, with highest expression levels found in liver. The AHR has been shown to play a role in the regulation/differentiation of Treg and Th17 cells.

The 4MEJJ monoclonal antibody has been found to recognize the b-1, b-2 and d alleles of mouse AHR but does not crossreact with human AHR.

Applications Reported: This 4MEJJ antibody has been reported for use in intracellular staining followed by flow cytometric analysis.

Applications Tested: This 4MEJJ antibody has been tested by intracellular staining and flow cytometric analysis of TH17 polarized mouse splenocytes using the Intracellular Fixation & Permeabilization Buffer Set (Product # 88-8824-00) and protocol. Please refer to Best Protocols: Protocol A: Two step protocol for (cytoplasmic) intracellular proteins located under the Resources Tab online. This can be used at less than or equal to 1 µg per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.

eFluor® 660 is a replacement for Alexa Fluor® 647. eFluor® 660 emits at 659 nm and is excited with the red laser (633 nm). Please make sure that your instrument is capable of detecting this fluorochome.

Excitation: 633-647 nm; Emission: 668 nm; Laser: Red Laser.

Filtration: 0.2 µm post-manufacturing filtered.

Target Information

AHR (Ah Receptor) belongs to a family of proteins comprised of its dimerization partner ARNT (HIF-1 Beta) and the Drosophila proteins PER and SIM. AHR contains an N-terminal sequence of approximately 200 amino acids termed the PAS domain. AHR, found in a variety of tissues, binds to a specific DNA enhancer sequence and initiates transcription of the mRNA for the cytochrome P-450 (CYPIA1) gene. The gene for AHR encodes a ligand-activated transcription factor involved in the regulation of biological responses to planar aromatic hydrocarbons. AHR has been shown to regulate xenobiotic-metabolizing enzymes such as cytochrome P450, and its ligands included a variety of aromatic hydrocarbons. AHR 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 AHR. 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, and this transformation process appears to involve dissociation of HSP90 from AhR followed by formation of a heterodimer with AhR nuclear translocator protein (Arnt). Diseases associated with AHR include eosinophilic fasciitis and seborrheic dermatitis.
