"TR-FRET TR alpha Coactivator Assay Kit, goat" | Creative BioMart

The TR-FRET TR (thyroid receptor) alpha Coactivator Assay Kit provides a sensitive and robust method for highthroughput screening of potential TR alpha ligands as agonists of ligand-dependent coactivator recruitment. The kit uses a terbium (Tb)-labeled anti-GST antibody, a fluorescein-labeled coactivator peptide, and a human recombinant TR alpha ligand-binding domain (TR alpha-LBD) that is tagged with glutathione-S-transferase (GST) in a homogeneous, mix-and-read assay format.
To Assay:
When performing the TR-FRET TR alpha coactivator assay, TR alpha-LBD is added to ligand test compounds followed by addition of a mixture of the fluorescein-coactivator peptide and Tb anti-GST antibody. After an incubation period at room temperature, the 520 nm/495 nm TR-FRET ratio is calculated and used to determine the EC50from a dose response curve of the compound. Based on the biology of the TR alpha-coactivator peptide interaction, the ligand EC50is a composite value representing the amount of ligand required to bind to receptor, induce a conformational change, and recruit coactivator peptide.
