Dipeptidyl peptidase-4 (DPP4, CD26) is a serine exopeptidase belonging to the S9B protein family. DPP4/CD26 acts as a positive regulator of T-cell coactivation, by binding at least ADA, CAV1, IGF2R, and PTPRC. It's binding to CAV1 and CARD11 induces T-cell proliferation and NF-kappa-B activation in a T-cell receptor/CD3-dependent manner. It acts also as a serine exopeptidase with a dipeptidyl peptidase activity that regulates various physiological processes by cleaving peptides in the circulation, including many chemokines, mitogenic growth factors, neuropeptides and peptide hormones.
The recombinant mouse Dpp4 (hFc Tag) consists 992 amino acids and predicts a molecular mass of 112.9 kDa. A DNA sequence encoding the mouse Dpp4 (Ser29-His760) was expressed with the Fc region of human IgG1 at the N-terminus.

| Recombinant Human DPP-4/CD26 Protein (HEK293, N-hFc)
Dipeptidyl peptidase-4 (DPP4) is a serine exopeptidase belonging to the S9B protein family. The enzyme is a type II transmembrane glycoprotein, expressed on the surface of many cell types. It is also present in serum and other body fluids in a truncated form (sCD26/DPPIV). As both a regulatory enzyme and a signalling factor, DPP4 has been evaluated and described in many studies. DPP4 inhibition results in increased blood concentration of the incretin hormones glucagon-like peptide-1 (GLP-1) and gastric inhibitory polypeptide (GIP). |
| Recombinant Human SOD1 Protein (E. coli, N-6His)
SOD1 binds copper and zinc ions and is one of three isozymes responsible for destroying free superoxide radicals in the body. SOD1 neutralizes supercharged oxygen molecules, which can damage cells if their levels are not controlled. The enzyme protects the cell against dangerous levels of superoxide. |
| Recombinant Human SOD2 (HEK293, C-6His)
SOD2 is a mitochondrial matrix protein that forms a homotetramer and binds one manganese ion per subunit. SOD2 transforms toxic superoxide, a byproduct of the mitochondrial electron transport chain into hydrogen peroxide and diatomic oxygen. |
| Recombinant Human MMP13 Protein (E. coli, N-His)
The MMP-13 protein plays a role in the degradation of extracellular matrix proteins, especially fibrillar collagen, fibronectin, TNC, and ACAN. It cleaves triple-helical collagen, preferentially cleaves type II collagen, and can also target other collagen types. |
| Recombinant Human DPP4/CD26 (HEK293, C-6His)
DPP4/CD26 is a signal-anchor for type II membrane protein that belongs to the peptidase S9B family. DPP4/CD26 acts as a positive regulator of T-cell coactivation, by binding at least ADA, CAV1, IGF2R, and PTPRC. It’s binding to CAV1 and CARD11 induces T-cell proliferation and NF-kappa-B activation in a T-cell receptor/CD3-dependent manner. |
