Inhibition of DEVDase activity in apoptotic thymocyte extract using PhiPhiLux™ substrate. An extract of mouse thymocytes exposed to 0.1 μM dexamethasone for 6 h was incubated in fluorometer cuvettes at 37°C with 10 μM PhiPhiLux™ substrate with or without the indicated protease inhibitors. Enzymatic activity was calculated from the rate of increase of fluorescence.
