Human CellExp DPPII / QPP / DPP7, human recombinant protein
DPPII, QPP, DPP7, DPP2, Dipeptidyl peptidase 2, Dipeptidyl aminopeptidase II
|Calculated MW||This protein is fused with polyhistidine tag at the C-terminus, has a calculated MW of 53 kDa. The predicted N-terminus is Gly 22. DTT-reduced Protein migrates as 60-66 kDa due to glycosylation.|
|Other Names||DPPII, QPP, DPP7, DPP2, Dipeptidyl peptidase 2, Dipeptidyl aminopeptidase II|
|Results||>4000 pmol/min/ µg.|
|Target/Specificity||DPPII / QPP / DPP7|
|Application Notes||Centrifuge the vial prior to opening. Reconstitute in PBS, pH 7.4. Do not vortex.|
|Storage||-20°C; Lyophilized from 0.22 µm filtered solution in 50 mM Tris, 150 mM NaCl, pH 7.5. Normally Mannitol or Trehalose are added as protectants before lyophilization.|

Dipeptidyl peptidase 2 (DPP2 or DPP II) is also known as Dipeptidyl peptidase 7 (DPP7), Quiescent cell proline dipeptidase (QPP), which belongs to the peptidase S28 family. DPP7 / DPP2 is detected in seminal plasma (at protein level). When the pH is 5.5, Dipeptidyl peptidase 2 displays an optimum catalytic activity. DPP7 has low activity at pH 7 and is inactive at pH 8. DPP7 plays an important role in the degradation of some oligopeptides.
