| | In Vitro GR Luciferase Reporter Assay |
| Description: | Cell Line: CHO-K1-GR-MMTV-Luc reporter cellsCulture Media: DMEM (with phenol red)+10% FBSAssay Media: DMEM (without phenol red)+10% CSSCulture CHO-K1-GR-MMTV-Luc reporter cells in 15 cm plates in Culture Media at conditions less than 90% confluence.Prepare 200×DMSO 1:5 serial dilutions of control and test compounds in 96-well non-sterile V bottom plate in DMSO, 8 serial dilutions for each compound.Prepare 5× Assay Media diluted compound serial dilutions in 96-well non-sterile V bottom plate: Add 97.5 uL/well of Assay Media into 96-well then add 2.5 ul of 200× concentration of compounds and mix well.Seed cells for Antagonist Assay: 1.5×106 CHO-K1-GR-MMTV-Luc reporter cells were seeded in a Corning 3707 flat clear bottom 384-well white TC plate in 20 ul of Assay Media containing 12.5 nM Dexamethasone (final concentration=10 nM).Add compounds: 5 ul of assay media diluted compounds were added to appropriate wells and followed a quick spin (1000 rpm, 10 sec) to bring media and cells to the bottom of plate. The plates were covered with SealMate film to avoid evaporation and placed in 37° C. incubator for approximately 18-24 hours.Read plates: Equilibrate appropriate amount of Promega OneGlo luciferase reagent to room temperature. Remove the plates from incubator and add 25 uL of OneGlo reagent/well by multiple channel pipette and read the plates with Tecan F500 luminometer within 3 minutes.The ability of the compounds disclosed herein to inhibit GR activity was quantified and the respective IC50 value was determined. |
