Anti-AHR Antibody, clone 1H8 ZooMAb^® Rabbit Monoclonal

Aryl hydrocarbon receptor (UniProt: P35869; also known as Ah receptor, AhR, Class E basic helix-loop-helix protein 76, bHLHe76) is encoded by the AHR (also known as BHLHE76) gene (Gene ID: 196) in human. AHR is a member of the periodic circadian protein (PER)-AHR nuclear translocator (ARNT)-single-minded protein (SIM) superfamily that serves as a ligand-activated transcription factor. It is reported to integrate environmental, dietary, microbial, and metabolic cues to control complex transcriptional programs in a ligand-and cell-specific manner. It is widely expressed and is detected in all tissues tested including blood, brain, heart, kidney, liver, lung, pancreas, and skeletal muscle. Its expression is also observed in retinal photoreceptors. AHR remains in an inactive state in a complex of HSP90, AHR-interacting protein (AIP), co-chaperone p23, and protein kinase SRC. Upon binding of an agonist, AIP dissociates from the complex that results in exposure of the AHR amino-terminal nuclear localization signal and an adjacent nuclear export signal. This allows AHR-ligand complex to translocate to the nucleus in a transportin-dependent and importin-β-dependent manner. In the nucleus, it heterodimerizes with ARNT and induces transcription by binding to xenobiotic response elements (XRE). Several xenobiotics are known to act as its ligands and xenobiotic-binding is known to activate the expression of multiple phase I and II xenobiotic chemical metabolizing enzyme genes. The AHR-ARNT heterodimer binds to core DNA sequence 5′-TGCGTG-3′ within the dioxin response element (DRE) of target gene promoters and activates their transcription. Mutations in AHR gene have been linked to retinitis pigmentosa 85 that is characterized by retinal pigment deposits and loss of rod photoreceptor cells followed by secondary loss of cone photoreceptors. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Clone 1H8 is a ZooMAb^® Rabbit recombinant monoclonal antibody that specifically detects Aryl hydrocarbon receptor (AHR). It targets an epitope within 22 amino acids from the C-terminal region.

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 µL.

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 µL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.

Reconstitute lyophilized antibody pellet with 25μL of ultrapure water or Phosphate Buffered Saline (PBS). Please refer to our reconstitution protocol and the specific application guidance on the suggested starting dilutions and sample type.
