Description
OverviewNative, DPP IV purified from porcine kidney (renal brush border of the proximal tubule). A serine exopeptidase dimer composed of two identical subunits of 110-130 kDa. Cleaves Xaa-Pro dipeptides from the N-terminus of oligo and polypeptides. DPPIV is involved in many cellular processes such as activation of cytokines, differentiation, T cell activation, and cell-matrix interactions. Inhibition of DPPIV has been reported to be an effective treatment for type II diabetes. MW: ~210000-260000 (unreduced).

Recommended reaction conditions
Activity Assay The specific activity can be assayed using the synthetic substrate, 7-(Gly-Pro)-amino-4-methylcoumarinamide, and the cleavage product, 7-amino-4-methylcourmain (AMC). Both are fluorescent, but the excitation/emission spectra are different; at an excitation/emission setting of 380 nm/460 nm, only the AMC product is measured. For quantitative measurement an AMC standard curve should be included; the recommended range is 100-800 pmol. Alternatively, the activity can be measured using the colorimetric substrate, H-Gly-Pro-pNA. The activity is then monitored at 405 nm over a period of time. A standard curve can be generated using 4-nitroaniline in the range of 5-100 nmol.
