Recombinant Human Dipeptidyl-peptidase 4, His-tagged

Specification :
| Cat. No. : DPP4-752H | Description : The protein encoded by the DPP4 gene is an antigenic enzyme expressed on the surface of most cell types and is associated with immune regulation, signal transduction and apoptosis. It is an intrinsic membrane glycoprotein and a serine exopeptidase that cleaves X-proline dipeptides from the N-terminus of polypeptides. | Source : S. frugiperda. | Purity : ≥90% by SDS-PAGE. | Form : Liquid. In 20 mM Tris-HCl, 5 mM CaCl2, 1 µM ZnCl2, 0.05% NaN3, pH 8.0. Please refer to vial label for lot-specific concentration. | Specific Activity : ≥8 U/mg protein. | Unit Definition : One unit is defined as the amount of enzyme that will hydrolyze 1 µmole H-Gly-Pro-AMC per min at 37°C, pH 8.0. | Toxicity : Standard Handling (MSDS available upon request). | Storage : ≤ -70℃.
