| | Androgen Receptor Binding Assay |
| Description: | Small molecules were tested for androgen receptor (AR) binding using a modification of the LanthaScreen TR-FRET Androgen Receptor Coactivator Assay (Thermofisher cat # A15878) where the fluorescein-labeled coactivator peptide was replaced with Fluormone AL-Red (Thermofisher cat #PV4294) to improve assay signal. Briefly, compounds were serially diluted in DMSO then transferred into assay buffer (Thermofisher cat # PV4295+5 mM DTT) at a 1:10 dilution. 10 μl of compound was transferred to a 96 half-area black well plate (Corning cat #3694) in duplicate. 5 μl of AR-LBD protein (5 nM stock in assay buffer; Thermofisher cat #3009) was added to each well. In addition 5 μl of a prepared stock of Fluormone AL-Red (20 nM) and terbium-labeled anti-GST monoclonal antibody (mAb) (30 nM; Thermofisher cat # PV3550) in assay buffer was also added to each well. Plates were incubated at room temperature (RT) for 6 hours then TR-FRET emission ratio was measured using an EnVision Multilabel Plate Reader (Perkinelmer #2104-0010) |
