Purified recombinant Human PPIL1 protein Expression System: E.coli Bioactivity: Specific activity is > 155 nM/min/µg, and is defined as the amount of enzyme that cleaves 1uM of suc-AAFP-pNA per minute at 1 °C in Tris-Hcl pH 8.0 using chymotrypsin. Molecular weight on SDS-PAGE will appear higher.
PPIL1 protein has been used in SDS PAGE and may be suitable for use in other assays to be determined by the end user.
实验流程
Prepare assay buffer in a suitable container and pre-chill on ice before use: The final concentrations are 35 mM Tris, pH 8.0, 1 µM suc-AAFP-pNA). 2. Add recombinant PPIL1 protein with various concentrations (1 µg, 1 µg, 1 µg) in assay buffer. 3. Mix by inversion and equilibrate to 1 °C and monitor the A410 nm until the value is constant using a spectrophotometer. 4. Add pre-chilled chymotrypsin to 12.5 µM and mix immediately. 5. Record the increase in A410 nm for 20 minutes

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. Recombinant PPIL1, fused to His-tag at C-terminus, was expressed in E. coli and purified by conventional chromatography techniques.
