Effect of La3+ (1.8 mM) on the potentiation of a BK-induced (20 nM) contraction of the guinea pig ileum by BPP9α (20 nM) in Tyrode-solution with (A) and without [Ca2+] (B). The arrows indicate the addition of BK, BPP9α, lanthanium or calcium ions. W = wash period. Curves are examples of five separate experiments.
