Human ERα Reporter Assay Kit
Product Description and Product Data
This is an all-inclusive cell-based luciferase reporter assay kit targeting the Human Estrogen Receptor Alpha (ER). INDIGO’s ER Alpha reporter assay utilizes proprietary mammalian cells that have been engineered to provide constitutive expression of the ER Alpha. In addition to ER Alpha 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 human ER Alpha. 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
Target Background
ER-alpha is encoded by the human gene ESR1 (Estrogen Receptor 1). The estrogen receptor (ESR) is a ligand-activated transcription factor composed of several domains important for hormone binding, DNA binding, and activation of transcription. Alternative splicing results in several ESR1 mRNA transcripts, which differ primarily in their 5-prime untranslated regions. The translated receptors show less variability.
INDIGO’s Estrogen Receptor Alpha Reporter Assay Systems utilize proprietary mammalian cells engineered to express constitutive, high-level expression of the full length Human Estrogen Receptor 1 (NR3A1), a ligand-dependent transcription factor commonly referred to as ERα.
INDIGO’s Estrogen Receptor Alpha Reporter Cells include the luciferase reporter gene functionally linked to an ERα-responsive promoter. Thus, quantifying changes in luciferase expression in the treated reporter cells provides a sensitive surrogate measure of the changes in ERα activity. Luciferase gene expression occurs after ligand-bound ERα undergoes nuclear translocation, DNA binding, recruitment, and assembly of the co-activators and accessory factors required to form a functional transcription complex, culminating in expression of the target gene. Unlike some other cell-based assay strategies, the readout from INDIGO’s reporter cells demands the same orchestration of all intracellular molecular interactions and events that can be expected to occur in vivo.
The principle application of this assay product is in the screening of test samples to quantify functional activities, either agonist or antagonist, that they may exert against the human estrogen receptor alpha.
