Introduction
CPPED1, a member of the metallophosphoesterase superfamily, plays a role in glucose uptake by fat cells. This protein binds to two divalent metal cations and is activated by the hepatitis B virus's large envelope protein.
Description
Recombinant human CPPED1, produced in E. coli bacteria, is a single chain of 337 amino acids (specifically amino acids 1 through 314) with a molecular weight of 37.9 kDa. A 23 amino acid His-tag is attached to the N-terminus of the protein, which is then purified using proprietary chromatographic techniques.
Physical Appearance
A clear, sterile solution that has been filtered.
Formulation
The CPPED1 solution (0.5 mg/ml) is formulated in a buffer containing 20 mM Tris-HCl (pH 8.0), 0.15 M NaCl, and 20% glycerol.
Stability
For short-term storage (2-4 weeks), the solution can be kept at 4°C. For longer storage, it should be frozen at -20°C. Adding a carrier protein (0.1% HSA or BSA) is recommended for extended storage. Avoid repeated freezing and thawing.
Purity
Purity is greater than 85% as determined by SDS-PAGE analysis.
Synonyms
CSTP1, Calcineurin-like phosphoesterase domain-containing protein 1, Complete S-transactivated protein 1, CPPED1.
