Binding
LANCE ULight TR-FRET Kinase Assay: CDK9 enzyme activities were measured using LANCE ULight TR-FRET kinase assay reagents (PerkinElmer, Waltham, Mass.). Compounds were directly added in 100% DMSO to white low volume assay plates (Perkin Elmer Proxiplate 6008289) using a Labcyte Echo acoustic dispenser. Assay reagents in serine/threonine kinase assay buffer containing 20 mM HEPES, 10 mM MgCl2, 100 mM Na3VO4, and 0.0075% Triton X-100. were added for final reaction mixture concentrations of 1000 uM ATP, 100 nM U-light MBP peptide (Perkin Elmer TRF0109M) and reaction initiated with 4 nM CDK9/Cyclin T1 (Carna Biosciences 04-110). The kinase reaction was carried out for 30 minutes before addition of stopping buffer to a final of 20 mM EDTA and 0.5 nM of LANCE Ultra Europium anti-phospho-MBP antibody (PerkinElmer TRF0201M) in LANCE detection buffer (PerkinElmer CR97-100). The reaction was equilibrated for 1 hour and the signal read in the Perkin Elmer Envision in TR-FRET mode.
