Assay Method Information

Assay Name:  TGM2 Inhibitory Activity Assay
Description:  2 ul of a solution of different concentrations of the test compound in dimethyl sulfoxide was added to 28 ul of buffer (50 mM TRIS, 100 mM NaCl, 10 mM CaCl2, pH 7.5) and 10 ul of a TGM2 solution to give a TMG2 test concentration of 25 ug/ml, and the mixture incubated for 15 minutes at room temperature in a 96 half-well microtiter plate. The enzyme reaction was started by the addition of 10 ul of substrate solution containing H-Abz-APE(CAD-DNP)QEA-OH and glycine methyl ester hydrochloride in buffer to give test concentrations of H-Abz-APE(CAD-DNP)QEA-OH of 50 uM and of glycine methyl ester hydrochloride of 5 mM. The time course of the reaction was monitored with excitation at 318 nm and measurement at emission wavelength 418 nm in a microtiter plate reader (SpectraMax M5, Molecular Devices) over 15 minutes. Rates were calculated from the linear part of the curve (generally between 5 and 10 minutes). IC50 values were calculated from the means (duplicates) of a dilution series of the com
