PROTAC IRAK4 degrader-3 (0.01~10 μM; 2 hours; PBMCs) mediated degradation is occurring in a proteasome dependent manner[1]. PROTAC IRAK4 degrader-3 (0.01~100 μM; 18 hours; PBMCs) is capable of completely blocking IL-6 secretion[1]. Western Blot Analysis[1]Cell Line: PBMCs Concentration: 0.01~10 μM Incubation Time: 2 hours Result: IRAK4 PROTAC-mediated degradation was occurring in a proteasome dependent manner.
