| Description: | 5 nM GST-CBP(1081-1197) and 20 nM biotin-H4(1-21) Ac-K5/8/12/16 (AnaSpec. 64989) were incubated with varying concentrations of CBP inhibitors in 15 μL of buffer containing 50 mM HEPES 7.5, 100 nM NaCl, 1 mM TCEP, and 0.003% Tween-20. After 30 minutes incubation at room temperature, 15 μL of detection buffer (BPS Bio. 33006) containing 7 μg/mL of Glutathione AlphaLisa acceptor beads (Perkin Elmer AL109) and 14 μg/mL of Streptavidin donor beads (Perkin Elmer 676002) was then added to the previous mixture. The reaction was incubated for an additional 2 hours at room temperature, and the AlphaScreen signal was quantified using the Envision Multilabel plate reader. As negative control, GST-CBP(1081-1197) was incubated with the non-acetylated biotin-H4(1-21) peptide(AnaSpec. 62555) and in presence of 0.25% of final DMSO concentration. |
