Recombinant Human Peptidylprolyl Isomerase (Cyclophilin)-Like 1, His-tagged

Cat. No.: PPIL1-333H
Product Overview: Recombinant PPIL1, fused to His-tag at C-terminus, was expressed in E.coli and purified by conventional chromatography techniques (174 aa, 19.3 kDa).
Description: Peptidylprolyl isomerase (cyclophilin)-like 1, also known as PPIL1, is a member of peptidyl-propyl cis-trans isomerase (PPIase) family, which catalyzes the cis-trans isomerization of proline imidic peptide bonds in oligopeptides and accelerates the folding of proteins. Human PPIL1 might play an important role in proliferation of cancer cells through modulation of phosphorylation of stathmin. So it is expected as a novel molecular target for colon-cancer therapy.
Source: E.coli.
Formulation: Liquid. In 20 mM Tris-HCl buffer (pH 8.0) containing 20% glycerol.
Molecular Weight: 19.3 kDa (174 aa).
Purity: > 95% by SDS – PAGE.
Concentration: 1 mg/ml (determined by Bradford assay).

Biological activity: Specific activity is > 300 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 PPIL1 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.
