General description

The Rac1/Cdc42 Activation Assay (Cat. No. 17-441) provides an effective method for detecting Rac and Cdc42 activity in cell lysates. This assay uses the downstream effector of Rac/Cdc42, p21-activated protein kinase (PAK1), to isolated the active GTP-bound form of Rac/Cdc42 from the sample. The p21 binding domain (PBD) of PAK1 is expressed as a GST-fusion protein and coupled to agarose beads. After precipitation, an immunoblot is performed and the activated Rac/Cdc42 is detected with specific monoclonal antibodies, followed by HRP-conjugated secondary antibody and ECL reagent.

Specificity

Species Cross-reactivity: Human and mouse. Predicted to cross-react with all mammalian species.
Anti-Rac1, clone 23A8: Species Cross-reactivity: Human, mouse and rat. Other species cross-reactivity unknown.
Anti-cdc42 Species Cross-reactivity: Human, mouse, rat and dog. Other species cross-reactivity unknown.

Components

Rac/cdc42 Assay Reagent (PAK-1 PBD, agarose), Catalog # 14-325 :One vial containing 300 μg of PAK-1 PBD bound to 150 μL of glutathione agarose beads, provided as a 50% slurry in 20mM PBS, pH 7.4, containing 50% glycerol for a final volume of 300 μL.

Anti-Rac1, clone 23A8, Catalog #05-389: One vial containing 250 μg of protein G purified mouse IgG2b in 250 μL of storage buffer (0.1 M Tris-glycine, pH 7.4, 0.15 M NaCl, containing 0.05% sodium azide).

Anti-cdc42, (mouse monoclonal IgG1) , Catalog # 05-542: One vial containing 50 μg of purified mouse IgG1 in 200 μL of 50% storage buffer (20 mM sodium phosphate, pH 7.5, 150 mM NaCl, 1.5 mM sodium azide containing, 1 mg/mL BSA) and 50% glycerol.

Mg2+ Lysis/Wash Buffer, 5X, Catalog # 20-168 : Two vials, each vial containing 18 mL of 5X MLB: 125 mM HEPES, pH 7.5, 750 mM NaCl, 5% Igepal CA-630, 50 mM MgCl2, 5 mM EDTA and 10% glycerol.

100X GTPγS, 10mM, Catalog # 20-176: One vial containing 50 μL of 10 mM GTPγS, 100X stock, in 50 mM Tris-HCl, pH 7.8, non-hydrolyzable analog of GTP. Sufficient to label 5 mL of cell lysates.

100X GDP, 100mM, Catalog # 20-177: One vial containing 50 μL of 100 mM GDP, 100X stock, in 50 mM Tris-HCl, pH 7.8. GDP (Guanosine 5′-Diphosphate) for in vitro labeling of G-proteins in the inactive form. Sufficient to label 5ml of cell lysates.

Quality

Routinely evaluated by precipitating Rac1-GTP and cdc42-GTP from 3T3/A31 and HeLa cell lysates that had been loaded with GTPγS(lysates were loaded in vitro with GTPγS for cdc42-GTP). The precipitated Rac1-GTP and cdc42-GTP was detected by immunoblot analysis using anti-Rac1 (1 μg/ml).
