show Abstracthide AbstractCHO-K1 cells were seeded into 6-well plates. After culturing for 24 h, the cells were exposed to 3,5-dibromo-2-hydroxybenzonitrile for 24 h at concentrations of 0 (negative control), 0.2 nM (environmentally relevant), 60000 nM (50% of EC20 value), and 120000 nM (EC20 value). Each concentration was tested in triplicate.
