Additional Information
This kit contains Rabbit Tb-Anti-GST antibody; other kit components are the same as kit PV4408:

The LanthaScreen® TR-FRET Estrogen Related Receptor (ERR) gamma Coactivator Assay Kit provides a sensitive and robust method for high-throughput screening of potential ERR gamma ligands as antagonists/inverse agonists of coactivator displacement. The homogeneous mix-and-read assay format results in a ligand EC50 composite value representing the amount of ligand required to bind to receptor, effect a conformational change, and displace coactivator peptide (Figure 1).

How it works

The LanthaScreen® TR-FRET ERR gamma Coactivator Assay Kit includes a terbium (Tb)-labeled anti-GST antibody, a fluorescein-labeled coactivator peptide, and a human ERR gamma ligand-binding domain (ERR gamma-LBD) that is tagged with glutathione-S-transferase (GST). To assay, ERR gamma-LBD is added to test compounds, followed by addition of a mixture of the fluorescein-coactivator peptide and Tb-anti- GST antibody. After room temperature incubation, the TR-FRET 520:495 emission ratio is calculated and used to determine the EC50 from a dose response curve of the compound.

Contents and Storage:
