Measurement of Eth in cell-attached patches from control and mdx muscle fibers. (A) Segments of current traces obtained in response to voltage pulses given at values indicated next to each trace from a holding potential of 0 mV. Asterisks indicate opening of KCa channels. (B) Segments of current traces obtained from the same patches shown in A after excision in the 2.5 mM Ca2+-containing bath solution. (C) Comparison of Eth in control and mdx cell-attached patches.
