Inhibition of TRPM7 channel activity by high Mg²⁺ concentrations; 56.5–145.2 μM free Mg²⁺ were applied to the patches followed by washout. Degree of inhibition was quantified as in Fig. 4. Representative traces chosen from three to seven patches for each Mg²⁺ concentration. Holding potential = −90 mV.
