This kit contains Rabbit Tb-Anti-GST antibody; other kit components are the same as kit PV6041:

The LanthaScreen™ TR-FRET ER alpha Competitive Binding Assay provides a sensitive and robust method for high-throughput screening (HTS) of ligands for estrogen receptor alpha (ER alpha). The kit uses a terbium-labeled anti-GST antibody, a fluorescent small-molecule ER ligand (Fluormone™ ES2), and a human ER alpha ligand-binding domain (LBD) that is tagged with glutathione S-transferase (GST), in a homogeneous mix-and-read assay format.
