Invitrogen™ PolarScreen™ Androgen Receptor Competitor Assay Kit, Green 

PolarScreen™ Androgen Receptor Competitor Assay Kit, Green

Manufacturer:  Invitrogen™ A15880

Catalog No. A15880

Description

The PolarScreen™ Androgen Receptor Competitor Assay Kit, Green, provides a sensitive and efficient method for high-throughput, fluorescence polarization-based screening of potential androgen receptor (AR) ligands. The kit uses insect cell-expressed, rat AR-ligand binding domain tagged with glutathione-S-transferase (GST) and histidine (also available separately), plus a novel, high-affinity, fluorescent androgen ligand (Fluormone™ AL Green) in a homogenous, mix-and-read assay format.

This kit produces a green color read-out; a 'red' kit is also available. Both kits suitably determine the IC50s of competitive compounds. Color choice depends on the spectral properties of the compounds to be screened and the available instrumentation.

The PolarScreen Androgen Receptor Competitor Assay is:

Complete & ready-to-use out of the box—all reagents included, just add your test compounds

High throughput compatible—fluorescence polarization assays in a 384-well plate

Convenient—components available in bulk sizes for larger screening needs

How the Assay Works
The kit uses the rat AR ligand-binding domain tagged with His and GST [AR-LBD(His-GST)]. AR-LBD(His-GST) is added to a fluorescently-tagged androgen ligand (FluormoneAL Green) in the presence of competitor test compounds in microwell plates. The presence of effective competitors prevents the formation of a AL Green/AR-LBD(His-GST) complex, resulting in a decrease of the polarization value due to ligand displacement caused by a competitor. The shift in polarization value in the presence of test compounds is used to determine relative affinity of test compounds for AR-LBD(His-GST).
