Material
The human Cdc42 protein has been produced in a bacterial expression system. The protein is supplied as a lyophilized powder. When it is reconstituted in distilled water to 1 mg/ml, the protein is in the following buffer: 2 mM Tris pH 7.6, 0.5 mM MgCl2, 0.5% sucrose, 0.1% dextran. Protein concentration is determined by the Precision Red Advanced Protein Assay Reagent, Cat. # ADV02.
The recombinant protein is 50 kDa, consisting of the 22 kDa Cdc42 protein plus a 28 kDa GST tag in the amino-terminus.
Purity
Purity is determined by scanning densitometry of proteins on SDS-PAGE gels. GST-Cdc42 samples are >90% pure.
Biological Activity
Biological activity of the protein is determined by demonstrating that in GTP bound CDG01 associates with PAK protein while the GDP bound form of CDG01 does not associate with PAK protein in a pull down assay.
