| Description | Stratifin Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 248 amino acids (1-248) and having a molecular mass of 27.7 kDa. Stratifin is purified by proprietary chromatographic techniques. |
| Expression host | Escherichia Coli. |
| Formulation | Stratifin solution containing 20mM Tris-HCl pH-8, 50mM NaCl and 10% Glycerol. |
| Protein Background | Stratifin is part of the 14-3-3 family. The 14-3-3 family of proteins plays an important regulatory function in signal transduction, checkpoint control, apoptotic and nutrient-sensing pathways. 14-3-3 proteins are highly conserved and ubiquitously expressed. There are 7 isoforms, beta, gamma, epsilon, sigma, zeta, tau and eta that have been identified in mammals. Stratifin is an epithelial cell marker that functions as a tumor suppressor whose expression can be down regulated via methylation. Failure of Stratifin expression results in a defective G2/M phase checkpoint and results in epithelial and non-epithelial tumorigenesis. |
| Purity | Greater than 95.0% as determined by SDS-PAGE. |
| Reagent Appearance | Sterile filtered colorless solution. |
| Stability | Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Avoid multiple freeze-thaw cycles. |
| Synonyms | 14-3-3 protein sigma, Epithelial cell marker protein 1, HME1, Stratifin, YWHAS, SFN, Stratifin. |
