Mouse AhR Reporter Assay System

This Mouse Aryl Hydrocarbon Receptor (mAhR) assay kit is an all-inclusive firefly luciferase reporter assay system that includes in addition to mAhR Reporter Cells, two optimized media for use during cell culture and in diluting the user's test samples, a reference agonist (MeBIO), Luciferase Detection Reagent, and a cell culture-ready assay plate. mAhR Reporter Cells are prepared using INDIGO's proprietary CryoMite(TM) process. This cryo-preservation method yields exceptional cell viability post-thaw, and provides the convenience of immediately dispensing healthy, division-competent reporter cells into assay plates. There is no need for cumbersome intermediate treatment steps such as spin-and-rinse of cells, viability determinations, cell titer adjustments, or the pre-incubation of reporter cells prior to assay setup. INDIGO's mAhR assay kits feature a luciferase detection reagent specially formulated to provide stable light emission between 5 and 90+ minutes after initiating the luciferase reaction. Incorporating a 5-minute reaction-rest period ensures that light emission profiles attain maximal stability, thereby allowing assay plates to be processed in batch. By doing so, the signal output from all sample wells, from one plate to the next, may be directly compared within an experimental set. mAhR assay kits are offered in different assay formats to accommodate researchers' needs: 3x 32 and 1x 96 assay formats for screening small numbers of test compounds, as well as custom bulk reagents for HTS applications. Protein function: Ligand-activated transcription factor that enables cells to adapt to changing conditions by sensing compounds from the environment, diet, microbiome and cellular metabolism, and which plays important roles in development, immunity and cancer (PubMed:10639156, PubMed:10973493, PubMed:1314586, PubMed:7961644, PubMed:7969080, PubMed:8806883, PubMed:9427285). Upon ligand binding, translocates into the nucleus, where it heterodimerizes with ARNT and induces transcription by binding to xenobiotic response elements (XRE). Regulates a variety of biological processes, including angiogenesis, hematopoiesis, drug and lipid metabolism, cell motility and immune modulation (PubMed:20106950, PubMed:28396409). Xenobiotics can act as ligands: upon xenobiotic-binding, activates the expression of multiple phase I and II xenobiotic chemical metabolizing enzyme genes (such as the CYP1A1 gene) (PubMed:10639156, PubMed:10973493, PubMed:1314586, PubMed:7961644, PubMed:7969080, PubMed:8806883, PubMed:9427285). Mediates biochemical and toxic effects of halogenated aromatic hydrocarbons. Next to xenobiotics, natural ligands derived from plants, microbiota, and endogenous metabolism are potent AHR agonists. Tryptophan (Trp) derivatives constitute an important class of endogenous AHR ligands. Acts as a negative regulator of anti-tumor immunity: indoles and kynurenic acid generated by Trp catabolism act as ligand and activate AHR, thereby promoting AHR-driven cancer cell motility and suppressing adaptive immunity. Regulates the circadian clock by inhibiting the basal and circadian expression of the core circadian component PER1. Inhibits PER1 by repressing the CLOCK-ARNTL/BMAL1 heterodimer mediated transcriptional activation of PER1 (PubMed:20106950). The heterodimer ARNT:AHR binds to core DNA sequence 5'-TGCGTG-3' within the dioxin response element (DRE) of target gene promoters and activates their transcription (PubMed:28396409).
