Channel conductance estimated for the SDBC

The minimum conductance and the related total number of channel insertions are shown. See text for the interpretation of gating.

Electrolyte	Minimum unit of conductancea	Estimated conductance from gatingb	Ion selectivity (Panion)	Total no. of channel insertions analyzed
	nS	nS
KCl	0.3	3	0.94	269
LiCl	0.25	2.5	1.86	158
CH3COOK	0.3	3	0.6	310

^a Channel conductance was estimated from the minimal unit of conductance observed.

^b Channel conductance was estimated from the gating pattern of the channel insertions.
