2.7. Measurement of DNA damage induced by FLUO

To evaluate DNA damage to Danio rerio larvae induced by FLUO, 8-OHdG contents and apoptosis were monitored. The supernatant was prepared from the homogenates prepared in Section 2.5 after centrifugation at 12,857g and 4 °C for 10 min. The esultant solution was kept on ice during the entire procedure. A prior study (Guo et al., 2014)noted the significance of 8-OHdG in evaluating DNA damage. The 8-OHdH contents were monitored using an 8-OHdG ELISA kit (Hengyuan Biological Technology Co., Ltd., Shanghai, China) at 450 nm for 10 min (Multiskan MK3, Thermo Fisher Scientific, Massachusetts, USA) and in units of ng/g protein. The total protein contents were assessed as in Section 2.6.As per Sun et al. (2019) and Wang et al. (2018), apoptosis was monitored using acridine orange (AO)-ethidium bromide (EB) double dyeing kit (Solarbio Science & Technology Co., Beijing, China). At 96 hpf, ten larvae from each trial in Section 2.5 were rinsed twice with PBS (pH =7.4) and dyed with 20 μL of AO and EB working fluid (1/1, v/v) for 5 min and then rinsed twice with PBS. Tritricaine (MS-222) was used for 3 min to anesthetize larvae for better observation. Then, the apoptosis of larvae was observed and photographed under an inverted fluorescence microscope (xioVert.
