Inbrief, 1106 cells in a 60-mm culture dish are incubated with 10 mM Valproic acid for 24 h. The cells are then

11、 washedin PBS and suspended in 5 volumes of lysis buffer provided with the kit. Protein concentrations are determined usingthe Bradford method. Supernatants containing 50 g total protein are used to determine caspase-3, -8 and -9activities. The supernatants are added to each well in 96-well microtit

After exposure to the designated doses ofValproic acid for the indicated times, MTT solution 20 mL: 2 mg/mL in phosphate-buffered

14、 saline (PBS) is added toeach well of the 96-well plates. The plates are additionally incubated for 3 h at 37C. Medium is withdrawn from theplates by pipetting and 200 mL DMSO is added to each well to solubilize the formazan crystals. The optical density ismeasured at 570 nm using a microplate reade
