AELL blocks high K+-evoked Ca2+ influx. a A representative tracing of 4 tracheal rings/4 mice. Under Ca2+-free conditions (0 Ca2+ and 0.5 mM EGTA), high K+ did not evoke contraction in a tracheal ring. After the restoration of 2 mM Ca2+, a sustained contraction occurred, which was partially inhibited by 17.8 mg/mL AELL. b Experiments were performed as described in Fig. 2a but with the order of high K+ and AELL (17.8 mg/mL) addition reversed. In the presence of 17.8 mg/mL AELL, a non-significant contraction was recorded after the restoration of 2 mM Ca2+
