Technical Data
Rac1 Inhibitor (NSC23766)
Biochemicals Storage: 4CShipping: Blue Ice
A cell-permeable pyrimidine compound that specifically and reversibly inhibits Rac1 GDP/GTP exchange activity by interfering with the interaction between Rac1 and Rac-specific GEFs (guanine nucleotide exchange factors) Trio and Tiam1 (IC50~50uM). Shown to effectively inhibit Rac1-mediated cellular functions in NIH3T3 and PC-3 cells (effective dose ~50-100uM). Exhibits no effect on Cdc42 or RhoA activation and does not affect Rac1 interaction with BcrGAP or PAK1. Reduces TRAP-induced and collagen stimulated platelet aggregation (IC50=50 mM and 64mM, respectively).

H2O (5 mg/ml)
