Fig. 13. Expression levels of tyrosine kinase (Syk) measured in untreated erythrocytes, or in 10 mM Mg²⁺-treated erythrocytes (control) or in erythrocytes treated with either 0.5 mM, or 1 mM, or 2 mM NEM (A) and treated with 10 mM Mg²⁺ + either 0.5 mM, or 1 mM, or 2 mM NEM treatment (B), detected by Western blot analysis. 10 mM Mg²⁺ n.s. not significant versus untreated; n.s. not significant versus control.
