Assay description: Quantification of degradation of fluorescently labelled BRD4 in HEK293 cells
HEK293 cells stably expressing N-terminal fluorescently tagged BRD4 variants were generated by stable integration of expression constructs into HEK293 wild-type cells. PROTAC-mediated degradation was measured by quantification of the tagGFP2-BRD4 fluorescence intensity after 24h compound treatment. For this, human embryonic kidney HEK293 cells (DSMZ ACC 305) stably expressing tagGFP2-BRD4 were seeded in 20 pi into 384- well microtiter plates (8000 cells per well) containing 200 nl_ of compounds in Dose- Response. Control wells received DMSO. Plates were then incubated for 24h at 37 °C in a humidified incubator and fixed with 1% PFA for 30 min. Cells were then stained with Hoechst 33342 (H-1399, 0.1pg/mL) and imaged on an automated confocal microscopy system. Nuclear and cytoplasmic intensity of the tagGFP2 fluorescence signal was determined by automated image analysis using custom generated scripts (MetaXpress). Data were then transferred to Genedata Screener software, normalized to DMSO and DCso values (half-maximal concentration to achieve maximal reduction of tagGFP staining intensity of the tagGFP2- BRD4 reporter fusion proteins relative to DMSO) are reported.
