Related Product Information for anti-DPP4 antibody
Dipeptidyl peptidase-4 (DPP4) or adenosine deaminase complexing protein 2 (ADCP 2) or T-cell activation antigen CD26 is a serine exopeptidase belonging to the S9B protein family that cleaves X-proline dipeptides from the N-terminus of polypeptides, such as chemokines, neuropeptides, and peptide hormones. 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). The soluble CD26 (sCD26) as a tumour marker for the detection of colorectal cancer (CRC) and advanced adenomas. 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). This causes an increase in glucose-dependent stimulation, resulting in a lowering of blood glucose levels. Recent studies have shown that DPP4 inhibitors can induce a significant reduction in glycosylated haemoglobin (HbA(1c)) levels, either as monotherapy or as a combination with other antidiabetic agents. Research has also demonstrated that DPP4 inhibitors portray a very low risk of hypoglycaemia development, and are a new pharmacological class of drugs for treating Type 2 diabetes.

Uniprot Description
DPP4: Cell surface glycoprotein receptor involved in the costimulatory signal essential for T-cell receptor (TCR)-mediated T-cell activation. Acts as a positive regulator of T-cell coactivation, by binding at least ADA, CAV1, IGF2R, and PTPRC. Its binding to CAV1 and CARD11 induces T-cell proliferation and NF- kappa-B activation in a T-cell receptor/CD3-dependent manner. Its interaction with ADA also regulates lymphocyte-epithelial cell adhesion. In association with FAP is involved in the pericellular proteolysis of the extracellular matrix (ECM), the migration and invasion of endothelial cells into the ECM. May be involved in the promotion of lymphatic endothelial cells adhesion, migration and tube formation. When overexpressed, enhanced cell proliferation, a process inhibited by GPC3. 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. Removes N-terminal dipeptides sequentially from polypeptides having unsubstituted N-termini provided that the penultimate residue is proline. Belongs to the peptidase S9B family. DPPIV subfamily.

Product Notes
The DPP4 dpp4 (Catalog #
AAA8111983) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The Recombinant Anti-DPP4/CD26 Antibody (APC), Rabbit Monoclonal reacts with Mouse and may cross-react with other species as described in the data sheet. AAA Biotech's DPP4/CD26 can be used in a range of immunoassay formats including, but not limited to, Flow Cytometry (FC/FACS/FCM). Researchers should empirically determine the suitability of the DPP4 dpp4 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process.
It is sometimes possible for the material contained within the vial of
"DPP4/CD26, Monoclonal Antibody" to become dispersed throughout the inside of
the vial, particularly around the seal of said vial, during shipment and storage. We always
suggest centrifuging these vials
to consolidate all of the liquid away from the lid and to the bottom of the vial prior to
opening. Please be advised that
certain products may require dry ice for shipping and that, if this is the case, an
additional dry ice fee may also be
required.
