Description: The FF3399 monoclonal antibody recognizes human 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.
Applications Reported: This FF3399 antibody has been reported for use in intracellular staining followed by flow cytometric analysis, western blotting, immunohistochemical staining of formalin-fixed paraffin embedded tissue sections, and immunocytochemistry (Fluorochrome-conjugated FF3399 is recommended for use in intracellular flow cytometry).
Applications Tested: This FF3399 antibody has been tested by immunohistochemistry on formalin-fixed paraffin embedded tissue using high or low pH antigen retrieval solutions (cats. 00-4955 and 00-4956) by immunocytochemistry on fixed and permeabilized human cells, and by western blot. FF3399 can be used at less than or equal to 20 µg/mL. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.
Purity: Greater than 90%, as determined by SDS-PAGE.
Aggregation: Less than 10%, as determined by HPLC.
Filtration: 0.2 µm post-manufacturing filtered.
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.
