(RARα, RARβ, RARγ), 3x 32-well assays
This PANEL of Retinoic Acid Receptors kit is an all inclusive assay system which includes in addition to reporter cells for each RAR, optimized cell culture medium, a medium for diluting test compounds, a control agonist for each RAR, stable-glow luciferase detection reagent, detailed protocol, Protocol Quick Guide, and a cell culture-ready assay plate in strip-well format so that (if preferred) RARα, RARβ, and RARγ assays may be performed at different times.
This PANEL contains sufficient materials to perform 32 RARα assays, 32 RARβ assays, and 32 RARγ assays in 96-well plate format.
RAR 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 plates. There is no need for intermediate spin-and-wash steps, viability determinations, or cell titer adjustments.
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.
Bulk assay reagents can be custom manufactured to accommodate any scale of HTS. Please inquire.
Retinoic acid receptors (RARs) are nuclear hormone receptors of the NRB1 class, which function as heterodimers with retinoid X receptors (RXRs). There are three distinct RAR subtypes; RARalpha, RARbeta and RARgamma. RARalpha is present in most tissue types, whereas RARbeta and RARgamma expression is more selective. RXR-RAR heterodimers act as ligand-dependent transcriptional regulators by binding to the specific retinoic acid response element (RARE) found in the promoter regions of target genes. In the absence of an RAR agonist, RXR-RAR recruits co-repressor proteins such as NCoR and associated factors such as histone deacetylase to maintain a condensed chromatin structure. RAR agonist binding stimulates co-repressor release and co-activator complexes, such as histone acetyltransferase, are recruited to activate transcription. RARs transduce retinoid signals in vivo, which mediates proper embryogenesis, differentiation and growth arrest. Specifically, RXRalpha-RARgamma heterodimers are necessary for growth arrest and viseral and primitive endodermal differentiation, whereas RXRalpha-RARalpha is required for cAMP-dependent parietal endodermal differentiation. In vitro it has been difficult to elucidate the roles of individual subtypes as functional RAR knockouts generate artificial redundancies that are thought not to exist under normal conditions.
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.
