Introduction
RhoB, a member of the Rho GTP-binding protein family, is involved in apoptosis regulation in cells undergoing neoplastic transformation after DNA damage. Notably, RhoB acts as a tumor suppressor, with its deletion potentially leading to tumor development.
Description
This Escherichia coli-derived RHOB protein is a single, non-glycosylated polypeptide chain with a molecular weight of 23.9 kDa. It consists of 213 amino acids, spanning positions 1 to 193, and includes a 20 amino acid His-tag fused at the N-terminus. Purification is achieved using proprietary chromatographic techniques, resulting in a highly purified protein.
Physical Appearance
Clear, colorless solution that has been sterilized by filtration.
Formulation
The RHOB protein is supplied in a solution at a concentration of 0.25 mg/ml. The formulation buffer consists of 20 mM Tris-HCl (pH 8.0), 2 mM DTT, 20% glycerol, and 0.2 mM NaCl.
Stability
For short-term storage (2-4 weeks), the protein solution should be stored at 4°C. For extended storage, it is recommended to freeze the solution at -20°C. To further enhance stability during long-term storage, consider adding a carrier protein such as HSA or BSA (0.1%). It is important to avoid repeated cycles of freezing and thawing.
Purity
The purity of the RHOB protein is determined to be greater than 90% based on SDS-PAGE analysis.
Synonyms
Rho-related GTP-binding protein RhoB, Rho cDNA clone 6, h6, RHOB, ARH6, ARHB, RHOH6, MST081, MSTP081.
