Recombinant Human Peptidylprolyl Isomerase D, His-tagged

Cat. No.: PPID-61H
Product Overview: Recombinant Human Cyclophilin-D produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 390 amino acids and having a molecular mass of 42.9 kDa. Cyclophilin-D is fused to His Tag at N-terminus and is purified by proprietary chromatographic techniques.
Description: Cyclophilin-D is a member of the peptidyl-prolyl cis-trans isomerase (PPIase) family. PPIases catalyze the cis-trans isomerization of proline imidic peptide bonds in oligopeptides and speeds up the protein folding. Cyclophilin-D possess PPIase activity and binds to the immunosuppressant cyclosporin-A. Cyclophilin-D is very well known that its overexpression suppresses the apoptosis in cancer cell. Cyclophilin-D suppresses apoptotic cell death by the use of mitochondrial hexokinase-2 dependent mechanism in cancer cells.
Source: Escherichia Coli.

Physical Appearance: Sterile filtered colorless solution.
Purity: Greater than 95.0% as determined by: (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.
Formulation: 1 mg/ml solution containing 1x PBS pH-7.4 & 10% glycerol.
Stability: Recombinant Human Cyclophilin-D although stable at 14°C for 1 week, should be stored desiccated below -18°C. Please prevent freeze thaw cycles.
Biological activity: Specific activity is > 210 nmoles/min/mg, and is defined as the amount of enzyme that cleaves 1umole of suc-AAFP-pNA per minute at 25°C in Tris-Hcl pH8.0 using chymotrypsin.
Activity Assay: 1. Prepare 170ul assay buffer into a suitable container and pre-chill on ice before use: The final concentrations are 200 mM Tris-Hcl, pH 8.0, and 20nM chymotrypsin.2. Add 10ul of recombinant Cyclophilin D protein with 1ug in assay buffer. 3. Mix by inversion and equilibrate to 1°C and monitor the A405nm until the value is constant using a spectrophotometer.4. Add 20ul pre-chilled 5mM suc-AAFP-pNA. (Substrate was dissolved in TFE that contained 460mM LiCl to a concentration of 3 mM)5. Record the increase in A405 nm for 30 minutes at 25°C.
Storage: Can be stored at +4°C short term (1-2 weeks). For long term storage, aliquot and store at -20°C or -70°C. Avoid repeated freezing and thawing cycles.
