RAR-related Orphan Receptor Alpha Background
RAR-related orphan receptor alpha (ROR-alpha), also known as NR1F1 is a nuclear receptor encoded by the RORA gene. The protein encoded by this gene is a member of the NR1 subfamily of nuclear hormone receptors. It can bind as a monomer or as a homodimer to hormone response elements upstream of several genes to enhance the expression of those genes. The specific functions of this protein are not known, but it has been shown to interact with NM23-2, a nucleoside diphosphate kinase involved in organogenesis and differentiation, as well as with NM23-1, the product of a tumor metastasis suppressor candidate gene. Four transcript variants encoding different isoforms have been described for this gene.
INDIGO's RAR-related Orphan Receptor Alpha (RORα) assay includes proprietary mammalian cells engineered to provide high-level expression of Human RORα. Human RAR Orphan Receptor Alpha Inverse Agonist Assay Reporter Cells also incorporate a responsive luciferase reporter gene. Quantifying expressed luciferase activity at the assay endpoint provides a sensitive surrogate measure of changes in RORα activity in treated cells. Endogenous molecular activators maintain RORα in a state of constitutive high-level activity. Therefore, the principle application of this reporter assay system is in the screening of test samples to quantify inverse-agonist or agonist activities that they may exert against human RORα.

RAR-related Orphan Receptor Alpha Assay Kit 
This RAR-related Orphan Receptor Alpha (RORa) assay kit is an all-inclusive assay system that includes, in addition to RORa Reporter Cells, two optimized media for use during cell culture and (optionally) in diluting the test samples, a reference inverse-agonist, Luciferase Detection Reagent, a cell culture-ready assay plate, and a detailed protocol.
RORa 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 ROR alpha 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.
ROR alpha 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.
Bulk assay reagents can be custom manufactured to accommodate any scale of HTS. Please inquire.
RAR-related Orphan Receptor Alpha Assay Kit
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.
