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.

Biological Activity

Molecular Weight

120-130 kDa

Purity

Greater than 95% as determined by reducing SDS-PAGE

Appearance

Lyophilized powder.

Formulation

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
