Steady-state activation and inactivation parameters of I_CaL in the absence and presence of 10 µM phenanthrene (Phe)

Activation			Inactivation
	Control	10 µM Phe	Control	10 µM Phe
V_0.5	−23.6 ± 1.3 mV	−24.9 ± 1.1 mV	−31.8 ± 0.1 mV	−32.0 ± 0.1 mV
k	5.1 ± 0.2	5.1 ± 0.2	1.4 ± 0.2	1.1 ± 0.1

Activation			Inactivation
	Control	10 µM Phe	Control	10 µM Phe
V_0.5	−23.6 ± 1.3 mV	−24.9 ± 1.1 mV	−31.8 ± 0.1 mV	−32.0 ± 0.1 mV
k	5.1 ± 0.2	5.1 ± 0.2	1.4 ± 0.2	1.1 ± 0.1

Parameters were obtained by fitting with Boltzman equation of individual activation (G/G_max) and inactivation (I/I_max) curves as described in Materials and methods. V_0.5, half-maximal voltage of activation and inactivation; k, slope factor. All values are presented as means ± SEM (n = 6; N = 2).
