Species
Human
Application
Useful for the study of enzyme kinetics, screening inhibitors, and selectivity profiling
Notes
PROTAC ternary complex formation with BRD3 and cereblon was assessed using AlphaScreen technology using FLAG-acceptor beads and GSH-donor beads. Various amounts of Cereblon were incubated in 10-ul reaction with 100 nM dBET1 and 15 nM GST-BRD3 BPS #31033 at room temperature for one hour. After this, FLAG-acceptor beads and GSHdonor beads were added followed by detection of A-counts.
