Assay Method Information

Assay Name:  Glucocorticoid Receptor Binding Assay
Description:  Small molecules were tested for glucocorticoid receptor (GR) binding using the Polarscreen Glucocorticoid Receptor Assay Kit, Red (ThermoFisher A 15898) according to the manufacturer's protocol. Briefly, compounds were serially diluted in DMSO then transferred into assay kit buffer at a 1:10 dilution. Compounds were further diluted 1:5 in assay kit buffer, and 10 μl was transferred to a 384 well low volume black walled plate (Corning 4514). 5 μl of 4×Fluormone GS Red stock solution and 5 ul of 4×GR full length stock solution were added to each well containing test compound, and plates were incubated protected from light at room temperature for 4 hours. Fluorescence Polarization (mP) was measured for each plate using an EnVision Multilabel Plate Reader (Perkinelmer #2104-0010), and data were analyzed using a four parameter curve fit to generate EC50 values.
