| | CBP Bromodomain Binding Assay (TR-FRET) |
| Description: | Compounds solutions of 10 mM in DMSO were pre-diluted in DSMO to 25× stock solutions in DMSO. These were then diluted down to 4× in Assay buffer. A dilution series in Assay buffer was performed keeping the DMSO concentration stable. 5 μl compound in assay buffer was transferred into the assay plate (provided by assay kit) and the TR-FRET assay Cayman chemicals; 600850) was performed using the manufactor's instructions. After 1 hour incubation at room temperature in the dark, assay plates were read in a Tecan M1000 plate reader using the TR-FRET mode (top read; excitation 340 nM bandwidth 20 nM; emission 620 nM bandwidth 7 nM; gain optimal determined for the first well, number of flashes: 5; flash frequency 100 Hz; integration time: 500 μs, lag time: 100 μs, room temperature). The TR-FRET ratio was calculated by dividing 670 nm emission by 620 nm emission. Calculation of EC50 was done on normalized values (DMSO=1) and positive control (0). Values were log transformed and non-linear regression with variable slope (4 parameters) was used to fit values to a dose-response curve to evaluate EC50 values. |
