Assay Method Information

Assay Name:  DPP-II Assay
Description:  Enzymatic reactions were conducted for various concentrations of DPP-IV inhibitors, using 0.018 μg DPP-II and 100 μM Gly-Pro-AFC in a buffer solution containing 50 mM acetic acid (pH 4.5) at room temperature. IC50 values of the inhibitors were determined by tracing the reaction rate using a fluorescence spectrometer for 60 min and analyzing the results using TableCurve 2D (v 5.01). DPP-IV inhibitors were analyzed using the fluorescence spectrometer at the excitation and emission wavelengths of 405 nm and 505 nm, respectively.
