一般描述
Rac1/cdc42 Activation Magnetic Beads Pulldown Assay (Cat. No. 17-10394) 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 magnetic beads. After magnetic rack separation, an immunoblot is performed and the activated Rac/Cdc42 is detected with specific monoclonal antibodies, followed by HRP-conjugated secondary antibody and ECL reagent.

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.
质量
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).
