Product Description and Product Data

This is an all-inclusive cell-based luciferase reporter assay kit targeting the Cynomolgus Monkey Pregnane X Receptor (cPXR). INDIGO’s cPXR reporter assay utilizes proprietary non-human mammalian cells that have been engineered to provide constitutive expression of the cPXR. In addition to cPXR Reporter Cells, this kit provides two optimized media for use during cell culture and in diluting the user’s test samples, a reference agonist, Luciferase Detection Reagent, and a cell culture-ready assay plate. The principal application of this assay is in the screening of test samples to quantify any functional activity, either agonist or antagonist, that they may exert against cPXR. This kit provides researchers with clear, reproducible results, exceptional cell viability post-thaw, and consistent results lot to lot. Kits must be stored at -80C. Do not store in liquid nitrogen. Note: reporter cells cannot be refrozen or maintained in extended culture.

Data

Agonist dose-response analyses of Monkey PXR. Performance of the monkey PXR assay using the reference agonists SR12813 (provided), hyperforin dicyclohexylammonium (Enzo Life Sciences), TO901317, rifampicin and dexamethasone (Cayman Chemical). Luminescence was quantified and average relative light units (RLU) and corresponding standard deviation (SD) values were determined for each treatment concentration (n ≥ 4). Fold-activation and Z’ values were calculated as described by Zhang, et al. (1999). Non-linear regression and EC50 analyses were performed using GraphPad Prism software. High Z' scores confirm the robust performance of this assay.

Target Background

Pregnane X Receptor also known as nuclear receptor subfamily 1, group I, member 2 (NR1I2) and SXR is a nuclear receptor that binds and is activated by variety of endogenous and xenobiotic compounds. PXR activates the transcription of multiple genes involved in the metabolism and secretion of potentially harmful xenobiotics, drugs, and endogenous compounds. Activated by the antibiotic rifampicin and various plant metabolites, such as hyperforin, guggulipid, colupulone, and isoflavones, its response to specific ligands is species-specific. PXR is activated by naturally occurring steroids, such as pregnenolone and progesterone and binds to a response element in the promoters of the CYP3A4 and ABCB1/MDR1 genes.

This assay product utilizes proprietary human cells engineered to provide constitutive, high-level expression of the Cynomolgus Monkey Pregnane X Receptor (nr1i2), a ligand-dependent transcription factor commonly referred to as PXR. PXR is also known as the Steroid and Xenobiotic sensing nuclear receptor (SXR).
