Concentration-response relationship for the effect of rottlerin (right panel, empty circles) and lack of effect of Ro 32-0432 (central panel, empty squares) on TTN 100 μM-induced [Ca⁺⁺]_i rise. Data are expressed as percentage of the effect of TTN alone (left panel, filled circle). Each point is the mean ± SD of 3 separate experiments.
