Introduction
Carboxypeptidase-E (CPE ) is a carboxypeptidase that cleaves C-terminal amino acid residues and is involved in the biosynthesis of peptide hormones and neurotransmitters. CPE is a peripheral membrane protein. CPE specifically connects regulated secretory pathway proteins, including prohormones, but constitutively secreted proteins. Mutations in CPE are implicated in type II diabetes.
Description
CPE Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 457 amino acids (43-476 a.a.) and having a molecular mass of 51.4kDa. CPE is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.
Source
Escherichia Coli.
Physical Appearance
Sterile filtered colorless solution.
Formulation
CPE protein solution (0.5mg/ml) contains 20mM Tris-HCl buffer (pH 8.0), 0.15M NaCl, 10% glycerol and 1mM DTT.
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.
Purity
Greater than 85.0% as determined by SDS-PAGE.
