Human RAR-related Orphan Receptor, Alpha Reporter Assay System

Assay kits include proprietary non-human 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 (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.

RORα 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 Catalog Nos. IB04011-32, IB04011, IB04012]
