RHEB Protein is stored in 50mM NaPhosphate pH7.0, 300mM NaCl, 150mM imidazole, 0.1mM PMSF, 0.2mM DTT, 25% glycerol. RHEB Protein is suitable for use in Western Blot and Kinase Assay. Expect a band approximately ~21kDa on specific lysates or tissues. Specific conditions for reactivity should be optimized by the end user.
