Introduction
HPGD, or 15-PGDH, is the primary enzyme responsible for prostaglandin degradation. It significantly reduces the biological activity of prostaglandins by catalyzing the oxidation of their 15-hydroxyl group into a keto group. This enzyme plays a crucial role in various physiological and cellular processes, including inflammation.
Description
This recombinant HPGD protein, expressed in E. coli, is a single, non-glycosylated polypeptide chain. It consists of 286 amino acids (residues 1-266), with a molecular weight of 31.1 kDa. The protein includes a 20 amino acid His-Tag at the N-terminus and is purified using proprietary chromatographic techniques.
Physical Appearance
Clear, colorless solution, sterile-filtered.
Formulation
The HPGD protein is supplied in a solution at a concentration of 0.5 mg/ml. The formulation buffer consists of 20mM Tris-HCl (pH 8.0), 0.1M NaCl, 1mM DTT, and 20% glycerol.
Stability
For short-term storage (up to 4 weeks), the product can be stored at 4°C. For extended storage, it is recommended to freeze the product at -20°C. Adding a carrier protein like HSA or BSA (0.1%) is advisable for long-term storage. Avoid repeated freeze-thaw cycles.
Purity
The purity of this protein is greater than 95%, as determined by SDS-PAGE analysis.
