Description: The human sCD26 ELISA is an enzyme-linked immunosorbent assay for the quantitative detection of human sCD26. The human sCD26 ELISA is for in vitro diagnostic use. Not for use in therapeutic procedures.
CD26, a T cell activation antigen, is a 110kDa cell surface glycoprotein with known dipeptidyl peptidase IV activity in its extracellular domain which is present on various cell types, including T cells and epithelial cells of the liver, kidney, and intestine. Of the T cell antigens described to date, CD26 has proved to be one of the most intriguing in the scope of its functional associations. Considerable evidence suggests that CD26 can deliver a potent costimulatory signal to T-cells. This signal transducing property appears to be a property of its extracellular domain. In addition, CD26 appears to be a functional collagen receptor that may aid activated T-cells in localizing to inflammatory regions. It has also been demonstrated that CD26 not only acts as a functional dipeptidyl peptidase IV, but also binds strongly to adenosine deaminase.
Significant levels of DPPIV activity have been shown to exist in plasma, serum, and urine. The serum form of DPPIV is unique, and is not a breakdown product of membrane CD26, nevertheless exposing significant structural similarity to the membrane form.
