Fig. 5. Expression levels of Band 3 protein measured in untreated erythrocytes, or in Mg²⁺-treated erythrocytes (control) or in erythrocytes treated with either 300 μM, or 600 μM or 1 mM H₂O₂ (A), or treated with 10 mM Mg²⁺ + either 300 μM, or 600 μM or 1 mM H₂O₂ (B) detected by Western blot analysis. 10 mM Mg²⁺ n.s. versus untreated erythrocytes; n.s. not significant versus control and ***p<0.001 versus control; ^§§p<0.01 versus either 300 μM, or 600 μM or 1 mM H₂O₂ alone.
