Development of inactivation properties of Nav1.5 co-expression of pIRES-GFP or FGF13 isoforms at −70mV and −90mV.

	Offset (%)	tau	n
−70mV Control	0.3 ± 0.2	31.9 ± 1.1	4
−70mV FGF13S	33.4 ± 0.1**	84.4 ± 11**	4
−70mV FGF13U	40.9 ± 0.2**	95.4 ± 7.6**	4
−70mV FGF13VY	26.3 ± 0.2 **	73.1 ± 7.3**	4
−90mV Control	42.7 ± 3	69.3 ± 11.8	4
−90mV FGF13S	83 ± 8.7**	164.9 ± 12.3**	4
−90mV FGF13U	90.8 ± 5.4**	153.3 ± 12.9**	4
−90mV FGF13VY	73.2 ± 10.2 **	268.1 ± 28.4**	4

Offset is the proportion of current that did not inactivate.

^**P < 0.01 compared to control at the same voltage.
