Product Introduction
Bioactivity
Name
NSC 23766 trihydrochloride
Description
NSC 23766 trihydrochloride (Rac1 Inhibitor) is an inhibitor of Rac GTPase targeting Rac activation by GEFs (IC50: ~50 μM); no inhibitory for the closely related targets, RhoA or Cdc42.
Cell Research
Cells (1.5 × 104/mL) are seeded in each well of 96-well tissue culture plates with 200 μL of medium. After 24 hours of plating, the medium is replaced with 200 μL of fresh medium containing NSC23766 at the indicated concentrations. At the end of the treatment period 20 μL of MTS solution are added to each well and incubated at 37 ℃ for 2 hours. Absorbance at 490 nm is read on a 96-well plate reader.(Only for Reference)
Kinase Assay
Rho GTPase activity assay: Cells are grown in log phase in a 10-cm dish, and are starved in 0.5% serum medium or indicated otherwise for 24 h before lysis in a buffer containing 20 mM Tris HCl (pH 7.6), 100 mM NaCl, 10 mM MgCl2, 1% Nonidet P-40, 10% glycerol, and 1× protease inhibitor mixture. Lysates are clarified, the protein concentrations are normalized, and the GTP-bound Rac1 in the lysates is measured by an effector domain pull-down assay. For the His6-PAK1 PBD pull-down assay, cell lysates are incubated with Ni2+-agarose-immobilized His6-PAK1 PBD domain (～1 μg each) purified from E. coli for 30 min. The Ni2+-agarose co-precipitates are washed twice in the wash buffer and analyzed by immunoblotting with anti-Rac1 monoclonal antibody.
