Product Summary

The Quantikine® Human DPPIV/CD26 Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human DPPIV in cell culture supernates, serum, plasma, saliva, and urine. It contains NS0-expressed recombinant human DPPIV, and antibodies raised against the recombinant factor. Results obtained using natural human DPPIV showed dose-response curves that were parallel to the standard curves obtained using the Quantikine® kit standards. These results indicate that this kit can be used to determine relative mass values for natural human DPPIV.

Recovery

The recovery of human DPPIV spiked to levels throughout the range of the assay in various matrices was evaluated.

Sample Type Average % Recovery Range %
Cell Culture Media (n=4) 101 87-113
Urine (n=4) 101 88-113

Linearity

To assess linearity of the assay, samples containing and/or spiked with high concentrations of human DPPIV were diluted with calibrator diluent to produce samples with values within the dynamic range of the assay.

Background: DPPIV/CD26

DPPIV/CD26 is a serine exopeptidase that is expressed as a noncovalent homodimer on the surface of epithelial cells, endothelial cells, and activated lymphocytes. It regulates multiple aspects of immune and endocrine function by cleaving Xaa-Pro or Xaa-Ala dipeptides from the N-terminus of a wide variety of chemokines (CCL4 and 5, CXCL6, 9, 10, 11, and 12), growth factors (GM-CSF, IL-3), and peptide hormones (Glucagon, Glucagon-like Peptides 1 and 2, GIP, GHRH, Procalcitonin, Neuropeptide Y, and Substance P). DPPIV interacts in cis with Adenosine Deaminase on T cells, in trans with Caveolin-1 on antigen presenting cells, and it serves as a cell entry coreceptor for HIV and coronavirus. It provides costimulatory proliferation and activation signals to both CD4+ and CD8+ T cells. A soluble form of DPPIV can be proteolytically shed from adipocytes, leading to insulin resistance in adipocytes and skeletal muscle.
