Material
The human Rac1 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 5 mg/ml, the protein is in the following buffer: 50 mM Tris pH 7.5, 0.5 mM MgCl2, 50 mM NaCl, 0.5% sucrose, and 0.1% dextran. Protein concentration is determined by the Precision Red Advanced Protein Assay Reagent, Cat. # ADV02.

The recombinant protein is 22 kDa, consisting of the Rac1 protein plus a histidine tag in the amino-terminus.

For other forms of Rac1 as well as many other purified small G-proteins, see our main small G-protein product page.

Purity
Purity is determined by scanning densitometry of proteins on SDS-PAGE gels. His-Rac1 samples are >90% pure.
