Analyses of cellular viability following exposure of ARPE-19 cells to inorganic mercury (Hg2+) as a conjugate of cysteine (Cys-S-Hg-S-Cys), homocysteine (Hcy-S-Hg-S-Hcy), glutathione (GSH-S-Hg-S-GSH) or HgCl2. Cells were exposed to various concentrations of each conjugate for 30 min at 37°C. Results are presented as means ± standard error. Data represent two experiments performed in quadruplicate. +, ++, +++, or ++++, significantly (p < 0.05) from the mean for cells of the same treatment group at the preceding concentration.
