Ice Packs
Catalogue Number PKA-357
Synonyms 14-3-3 protein sigma, Epithelial cell marker protein 1, HME1, Stratifin, YWHAS, SFN, Stratifin.
Introduction 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.
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.
Source Escherichia Coli.
Physical Appearance Sterile filtered colorless solution.
Formulation Stratifin solution containing 20mM Tris-HCl pH-8, 50mM NaCl and 10% Glycerol.
Stability Stratifin Human Recombinant although stable at 4°C for 1 week, should be stored desiccated below -18°C.
