(A) Single-channel current-voltage relationships for unmodified channels in the absence (•; mean ± SEM of 22–51 experiments) and presence (▴; mean ± SEM of 4–25 experiments) of 20 mM TEA+. (B) Single-channel current-voltage relationships for 21-amino-9α-hydroxyryanodine–modified channels in the absence (•; ± SEM of 4–15 experiments) and presence (▴; ± SEM of 4–10 experiments) of 20 mM TEA+. Where no error bars are visible they are contained within the symbol.
