Figure 4From: Duck Tembusu virus infection induces mitochondrial-mediated and death receptor-mediated apoptosis in duck embryo fibroblastsEffects of DTMUV on intracellular ROS in DEFs. A Assessment of ROS levels in DEFs using an intracellular ROS detection kit and fluorescence microscopy; the red colour indicates intracellular ROS. B Assessment of ROS levels in DEFs using an intracellular ROS detection kit and a multifunctional microplate reader. The data are presented as the means ± SEMs from three independent experiments; ** p < 0.01 and *** p < 0.001, compared with the control group.Back to article page
