Figure 3

Effect of metals other than zinc on oxidant-induced changes in TER and on Stx2 translocation. As in Figure 2, the “standard” concentration of hypoxanthine was 400 μM if not otherwise stated and the “standard” amount of XO was 1 U/mL. Panel A, lack of protection by FeSO₄ and MnCl₂ on oxidant-induced ∆ TER. Panel B, lack of protection by FeSO₄ on oxidant-induced Stx2 translocation. Panel C, lack of protection by MnCl₂ on oxidant-induced Stx2 translocation. Panel D, protection by CuSO₄ against oxidant-induced Stx2 movement across the monolayer.
