Purity: > 95% by SDS - PAGE Format: Liquid. In 20mM Tris-HCl buffer (pH7.5) containing 1 mM DTT, 1 mM EDTA, 10% glycerol . Rac1, belonging to the Rho small GTPase family, regulates the actin cytoskeleton but also other cellular processes. RAC1 have been shown to be involved in the regulation of cell-cell adhesion. Recombinant human RAC1, fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography techniques.
