Fig. 10. Percentage of membrane -SH groups measured in untreated erythrocytes, or in 10 mM Mg²⁺-treated erythrocytes (control), or in erythrocytes treated with 0.5 mM, or 1 mM, or 2 mM NEM with or without 10 mM Mg²⁺ (10 mM Mg²⁺+ 0.5 mM NEM or 10 mM Mg²⁺+ 1 mM NEM or 10 mM Mg²⁺+ 2 mM NEM). Bars represent the mean ± SD from at least 5 experiments. 10 mM Mg²⁺ n.s. not significant versus untreated, ***p<0.001 versus control; 10 mM Mg²⁺ + 2 mM NEM n.s. not significant versus control, °p< 0.05 versus 1 mM NEM, °°°p<0.001 versus 0.5 mM and 2 mM NEM.
