Fig. 3From: Effect of physicochemical character differences on the genotoxic potency of kaolinFCM analysis of incorporation rates of kaolins into mammalian cells. A549 and RAW264 cells were treated with two kinds of kaolin at several doses (20, 50, 100 and 200 μg/mL) for 30, 60 and 180 min. FCM analysis was applied to the cells to examine the incorporation rates. a Dose-dependent incorporation of kaolins (time duration was 180 min). b Time-dependent incorporation of kaolins (dose was 100 μg/mL)Back to article page
