This Estrogen-related Receptor Alpha (ERRα) kit is an all-inclusive assay system that includes, in addition to ERRα 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.
ERRα 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.
Kits are offered in different assay formats to accommodate researchers’ needs: 3 x 32, 1 x 96, and 1 x 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.
INDIGO's Estrogen-related Receptor Alpha assay systems utilize proprietary mammalian cells engineered to provide high-level expression of a hybrid form of Human ERRα (also known as NR3B1).
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 ERRα activity in treated cells. As is true in vivo, these reporter cells express ERRα in a constitutive state of high-level activity.
Therefore, the principle application of this assay system is in the screening of test samples to quantify inverse-agonist activities that they may exert against human ERRα.

Service Assays: Human
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.
