| Formulation |
CPE protein solution (0.5mg/ml) contains 20mM Tris-HCl buffer (pH 8.0), 0.15M NaCl, 10% glycerol and 1mM DTT. |
| Purity |
Greater than 85.0% as determined by SDS-PAGE. |
| 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. |
| Protein Background |
Carboxypeptidase-E (CPE ) is a carboxypeptidase that cleaves C-terminal amino acid residues and is involved in the biosynthesis of peptide hormones and neurotransmitters, including insulin. 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. |
| Expression host |
Escherichia Coli. |
| Synonyms |
Carboxypeptidase E, Carboxypeptidase H, CPH, CPE, CPE Human, Enkephalin convertase, Prohormone-processing carboxypeptidase. |
| 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. |
