CD26/Dipeptidyl Peptidase 4 Protein, Human (Biotinylated, HEK293, His-Avi)
The CD26/dipeptidyl peptidase 4 protein is a cell surface glycoprotein receptor that induces T cell proliferation and NF-kappa-B activation. CD26 also works with FAP to promote pericellular proteolysis, endothelial cell migration, and invasion of the extracellular matrix. CD26/Dipeptidyl Peptidase 4, Human (Biotinylated, HEK293, His-Avi) is the recombinant human-derived CD26/Dipeptidyl Peptidase 4 protein, expressed by HEK293, with N-6*His labeled tag.
- Species: Human
- Source: HEK293
-
Storage:Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Description
The CD26/dipeptidyl peptidase 4 protein is a cell surface glycoprotein receptor that induces T cell proliferation and NF-kappa-B activation. CD26 also works with FAP to promote pericellular proteolysis, endothelial cell migration, and invasion of the extracellular matrix. CD26/Dipeptidyl Peptidase 4, Human (Biotinylated, HEK293, His-Avi) is the recombinant human-derived CD26/Dipeptidyl Peptidase 4 protein, expressed by HEK293, with N-6*His labeled tag.
Background
CD26/Dipeptidyl Peptidase 4 protein, a cell surface glycoprotein receptor, plays a pivotal role in the costimulatory signal essential for T-cell receptor (TCR)-mediated T-cell activation. Functioning as a positive regulator of T-cell coactivation, CD26 interacts with ADA, CAV1, IGF2R, and PTPRC, leading to T-cell proliferation and NF-kappa-B activation in a T-cell receptor/CD3-dependent manner. Its binding to CAV1 and CARD11 induces T-cell proliferation, while its interaction with ADA regulates lymphocyte-epithelial cell adhesion. In association with FAP, CD26 is involved in pericellular proteolysis of the extracellular matrix, contributing to the migration and invasion of endothelial cells. Additionally, it may play a role in promoting lymphatic endothelial cell adhesion, migration, and tube formation. Acting as a serine exopeptidase with dipeptidyl peptidase activity, CD26 regulates various physiological processes by cleaving peptides in the circulation, including chemokines, mitogenic growth factors, neuropeptides, and peptide hormones. Notably, CD26 acts as a receptor for the human coronavirus MERS-CoV-2 during microbial infection.

Product Properties
Lyophilized powder.
<1 EU/μg, determined by LAL method.
It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).
Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
Room temperature in continental US; may vary elsewhere.
