Figure 3. Changes of CA-induced Ca²⁺ efflux in response to the addition of some inhibitors associated with Ca²⁺ flux.

All tested agents were added post incubation at 28°C for 200 s; ▽, 0.4 mM CA; Δ, 5 µg/mL Ruthenium red + 0.4 mM CA; ○, 5 µg/mL Verapamil + 0.4 mM CA. Verapamil and Ruthenium red, voltage-dependent calcium channel blockers. A representative trace of three repeats of each experiment was shown.
