The cell-membrane-permeable calcium probe quin2 acetoxymethyl ester (quin2 AM) was ineffective, in comparison with o-phenanthroline, in protecting cells against H2O2-induced DNA single-strand breakage at H2O2 concentrations of about, and higher than, 0.5 mM. The present study shows that quin2 actually
