This Human Nrf2 Assay kit is an all-inclusive, single use assay system which includes in addition to Nrf2 Reporter Cells, optimized media for use during cell culture and in diluting user’s test samples, a reference activator, Luciferase Detection Reagent, and a cell culture-ready assay plate.
Reporter Cells are prepared using INDIGO’s proprietary CryoMite™ process. This cryo-preservation method yields high cell viability post-thaw, and provides the convenience of immediately dispensing healthy, division-competent reporter cells into assay wells. There is no need for intermediate spin-and-wash steps, viability determinations, or cell titer adjustments prior to assay setup. Reporter Cells are single use reagents. They can not be refrozen or maintained in extended culture.
INDIGO’s 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.
Kits are offered in different assay formats to accommodate researchers’ needs: 3x 32, 1x 96, and 1x 384 assay formats for screening small numbers of test compounds, as well as custom bulk reagents for HTS applications.
Bulk assay reagents can be custom manufactured to accommodate any scale of HTS. Please inquire.
Nrf2 is a ubiquitously expressed, basic leucine zipper transcription factor. It regulates the expression of a variety of genes encoding proteins that play critical roles in cyto-protection, as well as the detoxification and clearance of harmful endogenous and xenobiotic substances. In particular, Nrf2 regulates the expression of antioxidant proteins that confer cyto-protection against oxidative damage.
Under normal conditions Nrf2 resides in the cytoplasm bound to Keap1 and Cullin 3, and is the target of ubiquitination and rapid turn-over via proteasomal degradation. However, under conditions of cellular oxidative stress the tight association of Nrf2 with Keap1 and Cullin 3 is broken, effectively disrupting the otherwise efficient process of Nrf2 degradation. Once non-ubiquitinated Nrf2 accumulates in the cytoplasm it translocates into the nucleus, whereupon it forms hetero-dimers with Maf. In this configuration Nrf2 binds to antioxidant response element (ARE) sequences resident in the promoter regions of some genes, initiating transcription complex formation and gene expression.
INDIGO’s Human Nrf2 utilizes proprietary mammalian cells that include the luciferase reporter gene functionally linked to a promoter containing tandem antioxidant response elements (AREs) and engineered to provide constitutive, high-level expression of Human Nrf2.
The principal application of this reporter assay system is in the screening of test samples to quantify functional activity, either agonist or antagonist, that may exert against Human Nrf2.

The primary application of INDIGO’s cell-based nuclear receptor assays are to quantitatively assess the bioactivity of a test compound as an agonist (activator) or antagonist (inhibition of an agonist response) of a given receptor. Service assays include a positive control reference compound and ‘vehicle’ control for every experiment.A formal study report and all data files are provided to the client upon completion of the study.

ABSTRACT The importance of gut microbiota in human health and pathophysiology is undisputable. Despite the abundance of metagenomics data, the functional dynamics of gut microbiota in human health and disease remain elusive. Urolithin A (UroA), a major microbial metabolite derived from polyphenolics of berries and pomegranate fruits displays anti-inflammatory, anti-oxidative, and anti-ageing activities. Here, we
