Purified recombinant Human FKBP2 protein Expression System: E.coli Bioactivity: Specific activity is > 150 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 pH8.0 using chymotrypsin.
FKBP2 protein has been used in SDS PAGE and may be suitable for use in other assays to be determined by the end user.
Procédure de l'essai
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 FKBP2 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

FKBP2 is peptidyl proline isomerase enzyme and a member of the immunophilin protein family. This protein is predominantly expressed in thymus and T cells and plays a role in immunoregulation and basic cellular processes involving protein folding and trafficking. It is a cis-trans prolyl isomerase that binds the immunosuppressants FK506 and rapamycin. FKBP2 is thought to function as an ER chaperone and may also act as a component of membrane cytoskeletal scaffolds. Recombinant FKBP2 protein was expressed in E. coli and purified by using conventional chromatography techniques.
